I have an installer that adds the installation directory to the PATH environmental variable, but by default you have to then restart the console session for that to take effect. That's inconvenient, especially in the context of something like winget. I should be able to do something like:
> winget install mything
> mything.exe
You can broadcast environment changes using the WixBroadcaseEnvironmentChange custom action.
However, it is ultimately up to the application (in your case probably cmd.exe) to listen for the broadcast message and to refresh it's settings.

I have an "Advanced Installer" project that I am trying to use to install my "TopShelf" windows service that I have built.
I found the spot in Advanced Installer to grant permissions to the installation folder, but I don't see a way to grant permissions to the "Local System" account.
Manually, this is done by going to the security option in the properties of the folder and adding a user with the same name as the computer name but ending with a $. For Example MyNiceComputer$. (Oh, and you have to select the "Computers" option in the types area.)
But there is no way to do all this in Advanced Installer. If I do make one like MyNiceComputer$, it just makes an empty entry in the security tab. (No Permissions on it, even though I setup for full control.)
Has anyone ever needed to do this with Advanced Installer?
Additional Details:
I am installing an app that runs as a windows service. (It is a console app built with TopShelf).
Our company policy is to install all our applications into a folder that looks like this:
C:\OurCompanyApps\MyApp
When I create the installer, it runs fine, but then I when I start up the Windows Service, I get the following error:
Windows could not start the MyApp service on Local Computer
Error 5: Access is denied.
But when I grant access to Local System (by giving Full Control rights to myNiceComputer$ on the MyApp folder), then this error goes away and the app runs fine. From what I read, this is because the application is running as Local System.
It seems odd that it needs full control but it does not work without it. (But as far as I can see, the contents of the folder are un-altered).
#Bogdan Mitrache seems to indicate that granting permissions to Local System is not possible via Advanced Installer. This is good to know (so I don't waste more time looking). I will probably ask my System Admins for a dedicated system account to run my service as. Not ideal, but it will serve as a work around.
So, in one of my "less finer" moments of debugging, I mixed up two different things.
There was also a file missing, (my config file). I restored that and changed the permissions at the same time. But then I forgot to go back and verify which one was the actual fix. (I know, not good debugging.)
So, the Access is denied error was due to a missing file.
I don't know why my system is only detecting environment variable of system and not user.
For instance, when I put "C:\Program Files\Java\jdk1.8.0_25\bin" as first environment variable in user environment variable , I was not able to run "javac" command.
But when I pasted it to system variable it started working.
I know about the dependency issues if I would have placed the path in user variable at the end so I put it at the beginning but still it didn't work..
I searched but found no real solution except dependency issue if I put it at the end.
Have you restarted the CMD?
Maybe you have to logoff & logon to refresh the user variables.
It least on my Windows 7 I have the same behavior, new user variable is not available.
So I have a web application running on Centos 6.5.
The application is a Ruby/Rails app, but the images are served by Apache HTTPD.
The application folder is in a user home folder, but I've granted HTTPD the correct permissions, and have enabled httpd_enable_home_dirs within SELinux. All static images are working just fine.
The problem I am seeing is when an end user uploads an image (A profile icon), the SELinux context for the file is getting set to unconfined_u:object_r:user_tmp_t:s0 instead of unconfined_u:object_r:usr_t:s0.
If I manually run restorcon on the file, the context gets fixed, and the image works. Any idea how I can make sure the file gets created with the correct context? I've looked into using restorcond, but it looks like it won't recursively check subdirectories, and the subdirectory structure is not predictable.
Any help is appreciated.
Most likely your application is moving 'mv' the object from /tmp, or /var/tmp to the destination location.
By default when a object is moved with 'mv', then so is its security metadata. Thus the object ends up at the destination with old and inaccurate security metadata. Running 'restorecon' on the destination objects resets the contexts to what the policy thinks it should be.
There are various ways you can deal with this. Either allow your webapp to read the object with the inaccurate context or tell your webapp to either use 'mv' with the -Z option, or use 'cp' instead. (the 'cp' command copies the object, and as a consequence the target object ends up with the appropriate security metadata, usually mostly inherited from the targets parent directory.
So apparently SELinux suppresses some error messages...
In order to debug this I had to run
semodule -DB
This rebuilds/restarts the local policy with the disable "don't log" flag. Once "don't log" is disabled, the error messages show up in the audit log and you can add a new policy using the regular:
sealert -a /var/log/audit.log
Then find the audit2allow command for the error in question.
You can set your logging back to normal after by running
semodule -B
I have a problem assessing my advanced settings of my computer, anytime i get to the properties of my computer it freezes and vanishes, I decided to set my path through the command prompt. Though the lines below works. Its just temporal and the path is unset immediately i close the running command prompt,
set path=%path%;C:\python27
I am just wondering why my computer's property panel vanishes.
Any others ways to set the environment variables permanent?
try using setx PATH "%PATH%;C:\python27"
Note that u need to close the current cmd window, after executing this command as the changes will reflect in newer instances only.
if i change hkey_current_user/environment/path in registry, get-env "PATH" doesn't reflect the new value unless I close rebol console and re_open it.
Environment variables are not the same things as Registry Keys.
Windows does consult particular registry keys when it is setting up the default environment a program gets when it launches from the shell. However, changing it won't inject those values into the environments of already running processes (in Rebol or any other program). Conversely, if you set things in the environment of a running program you won't see those changes reflected back into the registry.
If you want to read registry values, there is an API for that:
http://www.rebol.com/docs/sdk/registry.html
BUT rightly or wrongly: it is generally accepted (on every platform I've used) that one must exit a program and restart it in order to refresh environment variables from system settings. If you try and work around that, you may cause more complexity and confusion than anything else.
