I use Snipping Tool frequently and it no longer works on my Win 7 Ultimate machine. When attempting to open it, I get an error message to "restart your computer and try again". Of course, this does not work. I've just recently installed Office 2010 on this computer and I understand from other forums (which did not solve the problem) that this can cause the problem. One forum had a registry tweak to solve the problem, but I did not understand how to actually "import" the tweak. The tweak is as follows ...
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\AppID\{7F429620-16D1-471E-A81A-114992148034}]
