InstallAware

When I try to uninstall, it remove all the files including the file which are open in editor or used by other applications, in that case I want to display error and terminate the uninstallation.
How can I get 'File in use' information during uninstallation?

thanks in advance

Your best bet will be to write the functionality into a dll, then use Call DLL Function.

Both of these links suggest the same basic approach:
