OS is Windows XP, PRO with SP2.

I had problems with 7.5 and the "repair" option would not run (get error "not responding). I tried to uninstall and that would not run either. I finally had to manually delete Roxio, run roxizap and then I was able to reinstall my retail 7.0 version. However, I also have an ESD V7.5 (registered on this site) and when I try to install the 7.5 update (after restarting Windows), I get the following errors.

1. Unable to find a certificate file

2. There was a problem authenticating your version. Please make sure your system is set to the current date (which it is).

I thought the date may have something to do with when the ESD 7.5 was downloaded so I reset Windows XP (Pro) date back to when I downloaded the update but that wasn't the cause.

Edit, correction, this is an "upgrade", not an update. I should have noted that originally.

High Jack, don't see you around here too often!

That problem is usually related to the MS Installer. Try the cleanup utility, here, and see if that will fix it for you.

Jim, I haven't been around Roxio for a while and I'm on an old version.

The MS Installer cleanup didn't do anything for it. I ran the cleanup utility, restarted Windows and tried to install 7.5 again and got the same errors.

I also found another item about permissions, in the registry for Roxio, and tried that and it didn't help either.

This can be closed, although it wasn't resolved. I needed the Label Creator program so I backed up some important data then did a complete restore with my Acronis True Image. It was a last resort but needed to be done.
