Can't double-click Zip files anymore?

Having a wierd one on XP 64; I'm not sure when exactly it started occurring, but recently when I try to double-click a .zip file in Opus to look at it's contents, I get the attached error.

Not sure what it's really complaining about; I get it no matter what size the zip is (even 1MB or smaller) and I've got plenty of space on all HDs (minimum is 7GB+ on my System/C partition).

I am running the latest 9.5.0 but am not sure if this coincided with installing it. I am also running 7zip but turned off all it's shell integration and such, and it's not associated with .zip files.

Any ideas what I broke?[/img]

Try reinstalling Opus over the top of itself (don't uninstall first; there's no need to and it'll wipe your config if you do). That usually fixes issues with zip extraction on 64-bit machines. (For some reason the COM component registration gets broken for some people.)

That worked. Thanks!
