DRGScout
This is a silent installer and uninstaller for DRGScout 3.7.
First, do a "server installation". Then, use that path in INSTALLDIR= parameter to msiexec.
It looks that DRGscout.exe needs to be started as the first program from all other DRGscout programs - otherwise, these programs may report errors.
Also, you may want to see KODIP silent installer.
