Is there any conflict?
All new versions of Delphi can always be installed safely /next/ to older version.
Each new version should be installed in its own directory.
If you are going to install multiple versions, always install the oldest version first, and then work your way to the newest.
We work very hard to make sure that all versions of Delphi coexist together. But again, never install one version directly on top of another.
I am running 2007 and 2009 on the same machine (this machine) just fine. The only problem you might have is if you are compiling components to the same directory - you will just need to rebuild all your DCU's and packages each time, or make version specific packages and directories.
Install them in their own directories, and make sure you keep package binaries separate, you should be fine. I've got 2009, 2007, 2006, 7 and 5 all on this machine with no issues.
I have at least 4 Delphi versions on one machine. They do not bite each other.
I always install older versions first because i had once problems if i did this the other way round.
Yes - as Rob said (Robsoft) I have both working here. Delphi has always been very good at co-existing with other versions.
Obviously you can only have one version as the default for opening Delphi files.
Should not conflict.
I did D2007 on the same machine as D2006 with absolutely no problems (I was shocked, actually).
I haven't tried D2009 yet, but it should be ok.
This guy had problems though. Hopefully his issues were due to the custom setup he describes in that article.
A colleague of mine (think he has an account on here as dcraggs now) has got them both running on the same machine just fine, I believe.
Certainly would be a huge own-goal from Embarcadero if installing D2009 broke an already-installed D2007, given the way that the components and DCUs are not compatible - I suspect a fair number of people will need to have both around for a while (some of us still need D5 and D7 too!)
CodeGear stated (don't have a link handy, sorry) that there should be no conflict. I haven't yet installed D2009 on my workhorse PC so I don't know if that is correct.
The settings in registry have different path and packages have different names so there really should be no problems.
I have Delphi 2007 and I have installed 2009 yesterday with no visible problems so far. Both seem to work fine.
Appears to be no problem. Installed D2009 with TurboDelphi and 2007 and 2, 5 and 7 all on the same Vista machine
Both 2007 and 2009 have Jedi JVC and JVCL installed on them. All appear to work fine. Hope that helps.
.. and if you compile existing packages make sure you give them a new name (e.g. suffix with D12) as each version's BPL directories are in the path.
Installed D2009 Enterprise on VMWare instance running Vista Business with an existing D2007 Enterprise installation. Perhaps I did something incorrectly, but I began to experience errors in the D2007 IDE, as well as a very strange error, unknown fieldtype, in exe files compiled with D2007. I uninstalled D2009, and the errors have gone away.
You should always install the older version first. I tried to install 2009 first and then 2007 but the setup of 2007 failed.
Uninstalling 2009, and starting with 2007 first fixed the install problems.
In theory, it's possible, but if you use many third-party (or your own) libraries, it can get hairy pretty fast. I tend toward developing on Virtual machines, for this and other reasons. But, YMMV.
Should be fine. I have Delphi 7, 2006, 2007, 2009 with 3rd party libs Dev Express and Rem Objects for all (except Dev Express for 2009 - is it out yet?) and all work flawlessly. As others pointed out the versions were installed oldest to newest.
The installations won't interfere with each other, although the Delphi 2009 and Delphi 2007 projects are not compatible, and can't be shared.
Moving along with the order of release is a must. Install older first. Uninstalling may get tricky though.

I have to update a Delphi XE installation for a project to a newer version of Delphi but I don't have much experience with Delphi, the problem is there are plenty of old packages and components in there.
When I install a new version did I have to install all components again (if it possible to install it in this new version) or is it something like an update to my old installation and all installed stuff is now in the new version also?
Updating a Delphi XE application to a newer Delphi is usually quite easy. The only serious issue could be third party components which you must install in the newer Delphi version. Check with each component vendor that a version exists for your target Delphi version.
I always strongly recommand to NOT use any third party component that has no source available. Also don't buy any third party component using a DLL, OCX or other external binary object.
When you buy a third party component, always buy the source code with it. Then throw away any pre-build package or dcu and recompile everything before any serious use. That way you'll be sure to have all required source code and work with that source code.
Once you have the source code, it becomes much easier to port to the next Delphi version. Usually there is just nothing to change (There was only one notable exception in the past between Delphi 2007 and Delphi 2010 when Unicode string were introduced).
When there is something to change, it is usually only the name of a "used" unit. Somtimes Embarcadero move one class from a unit to another one. Sometimes, you have to change a $IFDEF which specify a Delphi version. Look at {$IFDEF VER180} and similar to adapt to you current version (See the online help for such symbol).
And if you still have issues, then ask here...
Upgrading to newer version of Delphi might not be a trivial task.
First problem you will run into are Thid Party Components.
If you don't own the souce code for them it means that they come with precompiled packages and these packages unfortunately arent compatible between different Delphi versions.
If you do have source code for them you might be able to recompile them on newer Delphi versions but this might require you to do some code changes.
So I strongly recomend you first check to see if there are updated versions of these components available that support the Delphi version to which you are planning to upgrade.
For instance if your application relies on BDE (Borland Database Engine) that shipped with older versions of Delphi you Will be forced to do Quite some changes to properly set up the FireDac database framework that ships with newer delphi versions.
My Win7 now installed RAD Studio 2010 with Delphi 2010, can I install Delphi XE3 separately? So both Delphi 2010 and XE3 work on the same Windows?
Thanks!
Yes you can. You can install all versions of Delphi side by side on a single machine. I'm currently sitting at a machine with D6, 2010, XE, XE2 and XE3.
Different people have different ways to organise side by side installations. I personally remove all references to Delphi from my system PATH variable. Then if I need to do anything at the command line I make sure I execute the rsvars.bat for the target version. That sets all the environment variables needed for that Delphi version. At that point executing dcc32.exe results in the target version of the command line compiler being invoked.
They should work. However some certain components might be buggy like different versions of BDE or maybe different versions of remote debugger core. But in general if you install lesser version with updates and then install more newer one - it should work. Unless some bugs happen.
But when you'd compile your projects or libraries, if you want to use both IDEs you should be very accurate about DCU and DCP paths, BPL names and such, so they would not be mixed in same place. DCU and DCP should be written into and searched in different folders. BPL names should have version-denoting suffix to them. and such.
I just bought Delphi XE2 starter and want to upgrade my projects. One of them is failing because Delphi doesn't know what TAdoConnection is.
I stupidly didn't keep a copy of the package when I D/Led it a few years ago now can't remember where I cgot it from
How to install TAdoCOnnection et al into Delphi XE2? Thanks
Update: alas, I have the Starter edition (who can afford anything else?)
Later update, just in case anyone else wants to do some database stuff with a starter edition.
I paid for AnyDac and was very happy, but then it was bought by Embarcadero, so you can't purchase it separately any more. I have a bug with Sqlite, so am looking for alternates.
Start here http://www.freebyte.com/programming/delphi/#freedelphidatabasecompone
ZeosLib looks very promising http://zeoslib.sourceforge.net/portal.php
It comes with Delphi, as long as you don't just have the "starter" edition, so you should already have it installed. Look in the ADODB unit. There is no other package to download.
It should be there, under ADODB:
http://docwiki.embarcadero.com/VCL/en/ADODB
http://docwiki.embarcadero.com/VCL/en/ADODB.TADOConnection
http://docwiki.embarcadero.com/CodeSamples/en/ADOQuery_%28Delphi%29
ADDENDUM:
Here's the XE2 feature matrix:
http://www.embarcadero.com/images/Delphi/delphi_short_feature_matrix_large.png
ADO is available on all versions ... EXCEPT the "starter version".
Since you have the Starter version, there is no direct option for TADOConnection. You either upgrade your version of Delphi, or use something other than TADOConnection.
During rebuild after a computer crash, I re-installed Delphi 7, then Delphi 2007. We skipped installation of Delphi 2006. However, now I would like to install Delphi 2006 before Embarcadero discontinues allowing for download of the latest version of D2006.
Is it possible to install Delphi 2006 on this computer without having an adverse impact on the other two installations?
My only concern is the potential problem of mixup in the SYSTEM PATH variable, where each version of Delphi uses the system PATH value to remember the location of the BPL files. Then the system PATH statement holds multiple BPL path locations created by each Delphi installation. However, each version Delphi only finds and uses the FIRST BPL path found in the list of paths - which always happens to be the most recent install. (Delphi installs insert - rather than append - the BPL path references at the beginning of the current system PATH value.) If this happens, then it is possible, for example, for Delphi 7 to reference the BPL files of Delphi 2007. Of course, that's not good at all. This is something that I know how to work around - if it is the only issue.
I'm hoping that the answer is not "uninstall Delphi 2007 first." That is painful for me as it takes significant time to re-install all the add-on components.
I have installed Delphi 5, Delphi 2006, Delphi 2007 and Delphi 2009 in various orders on several computers (laptop, work machine, home desktop, etc.) and have been fine.
I believe since 2007 is based on the 2006 version, that installing 2006 after 2007 is installed will most likely cause some problems. If you absolutely have to have a copy of 2006 for testing purposes, I strongly recommend setting up a virtual machine using VMWare or Virtual PC. This will allow you to test against 2006 directly...if you have 2006 and 2007 installed on the same machine, then your not testing 2006... your testing 2006 with 2007 installed.
I need to migrate to RAD Studio and have this installed on a new workstation. At the moment I still need to develop with Delphi 6 until we get all the necessary control updates and sort out the version control.
So my question is can I just install Delphi 6 on the same machine with no adverse impact for either product?
Thanks in advance.
There are no problem to install D6 and RAD 2009 at the same machine.
I think that it's better install first the previos version (first D6 and after D2009), but it's not absolutly necesary.
Regards and excuse for my bad english.
Installing them on the same system is no problem at all.
For migration, our clients have good experience with migrating to Delphi 2007 first, then do the Unicode migration to Delphi 2009 or Delphi 2010 second.
Doing both migration at the same time can work, but usually result in a migration that is too complex to do in one step.

I have delphi 3 to 2009 installed in my machine and I dont have any problem with any of the the Delphi IDEs. Only the BDS 2006's C++ IDE does not work anymore. There is a problem when C++ builder 2006 and 2007 installed in the same machine.
