No worries but again you've indentfied the problem yourself and its not a GameEx issue. Its the hitman software.
I'm probably going to lock the topic soon. Again nothing to do with GameEx.
Most good virus software allows you to exclude a folder from scanning but I've never even heard of hitman until now.
The issue is probably because the SetupWizard is set to launch as admin from a batch file. Its not supposed to do that anymore with recent versions of GameEx but its not a bug for me to fix.
