The past couple of days my computer will not let me into any program. For example - I'll try to double click on the Firefox shortcut, it gives me the error msg saying "this file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel".
There are many programs that will not open anymore and all give the same error msg. I have been searching online trying to find an answer. Please help. Thanks
