Problems upgrading from Winzip 11.1 to 11.2May 13, 2008 at 8:51 pm | Posted in Why was it so hard | 1 Comment
It should have been easy (famous last words). No uninstall required. Just install over the top and you’re done.
Unfortunately I hit problems immediately. A cryptic error message appeared along the lines of not having permission to access the following key.
This doesn’t make any sense. I’m running XP with full admin rights.
This one error causes the entire installation to abort.
So I thought I’d try removing Winzip 11.1 first. Same error.
However now I’m even worse off. Winzip 11.1 has now been partially removed, so I can no longer access it.
Run Regedit.exe (Start->Run and type regedit.exe) and manually remove the entire parent key
Run the uninstall again.
This time it comes up with the same error but for a different registry key
So I removed that key and tried again.
To cut a long story short, by repeatedly running the uninstall and then manually deleting each key that it complained about (approx. 5 or 6), I was able to get the uninstallation of 11.1 to complete.
I then ran the 11.2 installation which completed without errors.
It could have been much worse. I just hope every Winzip user doesn’t run into this problem or there are going to be a lot of frustrated people out there.
