I learned some time ago that some antivirus programs would pick this program up as a virus. It's because it modifies the Windows shell. Some virus scanners think, for good reason, that this is bad. It is bad, if the person intends to be malicious with your system. So, it is picked up as a virus. Rest assured, I don't plan on hurting any computers that aren't my own.
For the missing/damaged archive message, it is possible that either your download did not complete fully, for some reason, or the antivirus you used removed one of the files in the archive. I suggest deleting the old copy and redownloading it. Try it then, and tell me if it works. If not, I'll give you the files seperately.
As for the glass effect, that had been a goal for quite a while, but I found that it wasn't possible with AutoHotKey, the programming language I used to code the program. It hasn't been updated for Windows 7, and I don't have a computer that can handle Aero effects, so I cannot do this. Sorry.
Well, hope this helps.
