If I click on any programs it pops up and tells me that there is no association. I know how to association a file extension normally. If I click on Excel it gives me the error. Yet if I click on an Excel file then it will open the file. If I click on Notepad gives me the association error yet again if I click on a file saved in Notepad it opens that file. I tried to run System Restore but I get the same error. The exact error message is : This file does not have a program associated with it for performing this Acton. Create an association in the Folder Options control Panel. I notice when I go there there is no file extension for .exe. Not sure if there supposed to be one. I going to start up my laptop to compare. IN the meantime thought I post this question just in case. Do I need to run System Restore and how can I do this - I hoping not to reinstall Windows XP Professional - that is my operating system. I assuming I can re-install all programs but hoping this isn't necessary.
