Hi x-perts,
1) I have a custom action that runs an executable file at the end of installation. now I need it to run ONLY, if the user selects a certain feature.
What should be the Instal Exec Condition in that case?
The IS manual says "Windows Installer defines conditions of the form &FeatureName=n to detect a features action state." where an I get n-values for different feature states?
2) Also, I have an Environment variable that should be defined as well only, if a customer selects a certain installation feature. How can I do this?
the environment variables have an option of setting Component. Does this mean that if I link it with a component associated with that feature, the variable will be set only, if a customer selects that feature?
Please advise
Thanks

Thank you. Here is my case:
1) the application "test.exe" should run ONLY, if user selects the feature "Solver" for installation
2) It should not run during uninstallation
Currently, I am using condition like
Remove <> ALL
What should I write to add a feature-dependent install?
Remove<> ALL & Solver = 3
Correct?
Can I combine these two conditions like that?
i didnt get your question, test.exe is a installer or application ?
you should throw a error when installing it self .
i had the similar problem some year back , if user select first feature then only installer should continue .
so i added the condition like "&Server = 3 or (!Server = 3 and &Server<>2) " in Next button .
sorry for misunderstanding. Test.exe is a standalone application that should run once during installation (not uninstallation). It works OK for me with a condition
Remove<> ALL
which prevents it from running during uninstall. Now I need only one thing: to restrict its execution only for a selected feature (named Solver)
so, is "Remove<> ALL & Solver = 3" correct?
OK, what happens, if the user doesn't select solver feature?
1) Obviously, the test.exe will not run during install, which is correct
2) what about uninstall, if Solver wasn't selected during install? are you sure that "test.exe" it will not run?
I am asking, because I cannot understand what will be the value of Solver during uninstall, if it was not selected during install....

You can write like this " &Server = 3 or (!Server = 3 and &Server<>2) "
in above example '&' means the present status of the feature ( after the user modification)
'!' means status of the feature in the system
3 is install
2 is uninstall
so in above case user request for install the feature "Server" ( &Server = 3 ) OR
and in the case of modification old status is installsed and now he is not uninstalling .
