No, it can't. It comes up with "unknown file type." I don't think UniExtract2 is to blame here. I think the pov.exe file is malformed for an installer. I watched UniExtractor try every method in its arsenal, and it couldn't make sense of pov.exe. If UniExtract2 works on standard installation executables perfectly well, but fails on non-standard ones, I don't think UniExtract is at fault.

Maybe better write in https://github.com/Bioruebe/cicdec , but similar question is unanswered.
