I am testing building a package with epilog that would install epilog for Windows 1.6.0 and would load the registry keys needed. Unfortunately, I have noticed that the logs are all in the same relative locations %SystemRoot%\folder, but not all Windows systems use C:\Windows\, some are using a system path instead of C:\Windows or a different drive letter altogether. Instead of coding for if directory exists then do something for every possible scenario that could exist, is it possible to use the %SystemRoot% variable in the registry key instead? That way, I could have the one installer and would only need to give the path to the log files as %SystemRoot%\folder\file.log? Thanks.
