My PC currently has Delphi 2005 installed. Can Rad Studio XE6 be installed on this same PC without issue? Or, is it a case of one of the other?
Yup, each installation is completely independent of the other. The only caveat is that the file associations will only go to one version -- which will be the latest one unless you disable setting them when you do the install.

So I have Delphi XE (no number) and I have a project that was built on another machine (using JVCL components). Now, my machine is a Windows 8.1 (64 bits), and the previous machine was Windows XP (32 bits).
Of course I want to be able to continue developing the app, but for that I need the JCL/JVCL to be installed here too.
Now comes my problem. When I run the installer (bat) of JCL, it starts ok, but it does not show any options, so when I click the Install button nothing happens, and I get a message saying the installation finished. But of course nothing is installed.
This is how the installer looks on my x64 machine:
What can I do to install this JCL on a win64 machine? I am very sure that this is the problem: the OS. Because on 32bit OS (Windows XP) I have no problem installing it.
I looked it up, but could not find a straightforward solution. There might be a problem with some registry where the installer looks for the location of Delphi ?!?! but I have no idea how to fix it.
I need to install the JVCL, but it wont install unless I have JCL installed first... and the JCL does not install
Please help me.
Thank you
here is a problem I meet. I download and installed WampServer, it could not be started. After clicking, it started without any error message but ended immediately because
there was an WampServer icon in the right-down corner (just besides input icon and time) and disappeared within less than 1 second automatically. No process of wamp can be found when using ctrl+alt+del.
I suppose there is no problem in wampserver software itself since it can be installed in other computers successfully. Previous searching indicated I need to install visual C++ 2008 and 2010 but it seems still the same.
I am going crazy about this for a few days. Many thanks for you if there can be any suggestion or some similar cases.
Please make sure you have the latest version of all of these Microsoft C/C++ Redistributable runtime libraries. You dont need the whole compiler, just these C/C++ runtime libraries.
The 2008 Redist (32bit) is used by wampmanager even if you installed the 64bit WAMPServer.
The 2010 Redist is used by some versions of Apache ( depending on compiler used ).
The 2012 Redist is used by some versions of Apache ( depending on compiler used ).
FOR WAMP 32bit
Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)
Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)
If you are using WampServer2.4/2.5 32bit and therefore Apache 2.4.x
Microsoft Visual C++ 2012 is required
And select vcredist_x86.exe
FOR WAMP 64bit
Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)
>> Yes you need the x86 Package regardless as wampmanager uses this <<
Microsoft Visual C++ 2008 Redistributable Package (x64)
Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)
If you are using WampServer2.4/2.5 64bit
Microsoft Visual C++ 2012
And select vcredist_x64.exe
the authors state directly on the download page (http://www.wampserver.com/en/):
Wampserver 2.5 is not compatible with Windows XP, neither with SP3,
nor Windows Server 2003
When I tried it, during the install I get the odd, cryptic error popups such as "bin\apache\apache2.4.9\bin\httpd.exe is not a valid Win32 application".
I would recommend doing the manual approach for Win2K3 platforms - sure it's a lot more work, but you can follow an excellent, precise step-by-step recipe here:
http://www.ricocheting.com/how-to-install-on-windows/apache
I've done this approach a dozen times with no complications. If you've never done the "old school way" before, it's a good learning experience. And it would probably be a lot faster overall than struggling with trying to get WampServer working on Win2K3 OS.
Note that in both cases, you'll still need to first install VC 2008 redistributable package (as mentioned above).
I have PostgreSQL 9.2 installed on win 7 64 and can connect to it with ODBC from my delphi IDE using dbexpress with no problem. When I try to connect using Zeos, and although I have provided the path to the libpq.dll, I still get the error (libpq not found or not loadable). I tried all solutions I found by googling but so far I haven't found a working solution.
I have put the dll, and later all dlls into system32 to even see if that is what it takes.
This is my setup:
Delphi XE3
Zeos 7
PostgreSQL 9.2
On windows 7 64
Does anyone use this system and can connect to postgresql 9.2 with zeos?If so what am I missing?
So my question summarized in one line is this:
What is a working configuration/steps to connect zeos 7 with postgresql on delphi on win 7 64?
Your answer is much much appreciated!!
Make sure you have the following files together with libpq.dll:
libeay32.dll, libiconv.dll, ssleay32.dll, libintl.dll, libxml2.dll,
and libxslt.dll. These are library files that lipq.dll depends on. Delphi IDE is 32bit so you can only use the 32bit version of the above libraries if you want to connect to postgresql at design time. If your project is 64bit you may get the 64bit version of the files above and place it in a separate folder under your project's root dir then change the libpq.dll path of ZConnection at runtime to point to that folder.
Hope this helps.
Are you sure your ZeosLib is x64? When building component, make sure you choose 64-bit Windows as Target Platform.
Most likely the computer where the problem is happening lacks Microsoft Visual C++ 2010 Redistributable x64. I adivise you to download it from Microsoft and install it, then run another test.
I had the same problem. To get around this, I had to change the working directory of the delphi application to the path of libpq.dll because otherwise it will not be able to find the other libraries, it needs. So maybe you want to do something similar to this before opening the first connection to postgresql:
OldPath := ExtractFilePath(Application.ExeName);
ChDir('c:\path\to\libpq\dll\');
ZConnection.Connect;
ChDir(OldPath)
Any advice or gotchas that I should be aware of. I know to install in a NEW directory, and to have a backup. I will reread the readme file that included in the Delphi-XE installer.
I've never had problems installing a new release of Delphi with an older version also installed. I have heard that you shouldn't do the opposite (install an old version with a new one already installed) but as far as I know, installing "forwards" works just fine. And specifically installing XE with D2010 already present has never given me any trouble either at work on on my personal system.
Ive had a number of machines with multiple versions of delphi on without issue, however if you are that concerned, a further thought or consideration is to virtualise your development environments as then rather than reinstall you can "copy" .. Ive put mine into the XP mode machine on my windows 7 for that very reason.
I recommend not installing in Program Files (x86). I created a folder C:\DEVTOOLS which has my Borland, Codegear and Embarcadero folders (among others). This is definitely the 'least fuss' option.
I want to install Rad Studio 2010 on a machine that already has installed Rad Studio 2007,
There is some compatibility problem?
thanks in advance, Bye.
See this answer from Nick Hodges.
There is no problem with installing a newer version of Delphi/RAD Studio on a machine that has an older version. As Mason says, the reverse is not necessarily true.
Trying to install an older version of Delphi when a newer version already exists can cause problems. If you have to have both, either put 2007 in a VM or uninstall 2010 and then install the two Delphis in order, which will work just fine.
