Installscript can be captured by Wise Package Studio by pre-scanning and then scanning messages. Basically, you pre-scan your system, which scans the registry, files, versions, odbc, etc. Then you install your software and do a post-scan, which does the same thing as a pre-scan. This method compares the two to find out what changes you have on your system.
Another method is to run the program on the first call, then click Start> Run>% TEMP%, then click OK. Keep track of this directory for any MSI files.
If you get .msi, you can use "Msiexec.exe / i nameOfFile.msi / qb" on the command line to silently install.
I assume you have a system administrator. Your question is great, I hope that I was able to add my 2 cents and contribute.
