My company like to package all applications with Wise Studio. Well we had mixed results with McAfee VirusScan 8.7. Initally it looked like the package was fine, but as the number of test machines grew we saw more failures.
Testing found that on machines where it failed, it would uninstall VSE 8.0 and start installing 8.7. It would fail to start the service. (Looked like the issue where the full path to system32 was not in the registry). As the packager stated, the wrapper just called setupvse.exe /passive
If I deploy the vendor installer with the passive switch we have 100% success.
