FileForums - Freearc/Innosetup decompressing error

I hope this is the right place to ask but I'm getting installation errors for some compilations which probably use freearc+innosetup utilities. I did some web searches but didn't find anything that could help me directly except for this forum.

2 example event logs errors(dashes are redacted portions):

Code:

Faulting application name: Setup.exe_Installer, version: 6.0.0.0, time stamp: 0x54359624

There seems to be an issue with cls-srep.dll. I'm running win10 x64 which was installed clean recently. Am I getting this error because of some missing runtime libraries?
