Гаден проблем, който наистина може да се получи след принудителен рестарт. Не смея дa предполагам, че в Win7 е бил направен опит да се реши. Виж тези 2 варианта, които се мяркат по форумите:
ВАРИАНТ 1:It's basically a registry value for each Program
Mine is 32-Bit OS it would be under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall some time it won't register properly
Highlight the Program Name
In the right-pane, do the following:
Double-click NoRemove (REG_DWORD) and set it to 0
Double-click NoModify (REG_DWORD) and set it to 0
If NoRemove is set to 1, the Remove button will be unavailable
If NoModify is set to 1, the Change button will be unavailable
You could also see them using Windows Installer Cleanup
-----------------------------------------------
ВАРИАНТ 2:
Control Panel - Programs and Features.
uninstall components - Programs and Features-Turn Windows Features on and off
or type appwiz.cpl in start menu search
