Well I just updated to Windows 7 Pro 64 bit version. Installed Impulse and redownloaded and installed my two favorite parts of Object Desktop. Object Edit and ObjectZip. OE works great, but OZ made all my zip files loose their zip icons. Is there going to be an update for ObjectZip to make it Windows 7 compatible? It also didn't apparently associate itself with zip files either.
I do not believe ObjectZip supports 64 bit and I would suspect it will not get an update as it is no longer part of ObjectDesktop for new customers. Windows 7 comes with its own built in .zip support already.
Yeah, I'm not really sure what kind of experience you would expect using ObjectZip on an OS beyond XP, as it became obsoleted some time ago now. I would suggest 7-Zip, it's a great archiver:
