I’ve had this problem for a while, but as I’ve not needed access to the Windows 8 UI or its apps, I’ve not worried about it – until now.
Turns out if you’re still using Corel DRAW X3 or X4, it mucks around with the Windows Registry and basically stuffs up the Windows 8 UI. Now while there are a few bigger-than-ben-hur solutions available, I’ve found a nice simple one that actually worked on the Microsoft community website. It does require fiddling around with the Windows Registry, but it’s a pretty simple fiddle as fiddles go (don’t blame me if you try this out and wake up with your computer busted and think it’s 1980 again…)
1. Open regedit.exe
2. Right click on HKEY_CLASSES_ROOT and select permissions
3. Add “All Application Packages” with Read permission (All Application Packages was missing)
The ‘All Applications Packages’ entry was indeed missing in my build – once returned, Metro apps began to work.
(Okay, I’m sure everyone reading this is a Photoshop junkie, but I’ll keep this here for my sake, if no-one else’s!)
