Error Message: I have noticed recently that on my Vista system, when I click on the Check for Updates option of CCleaner or IObit Advanced System Care, the update web site for the products used to open, but now Notepad opens.
In doing some research on the internet, I have found that there is a problem reported several times that when clicking on an EXE file, Notepad is called. This problem is apparently caused by an erroneous value Notepad.exe) in a Registry key. Sometimes this is caused by a virus, I read. I have scrupulously updated the OS and MSE. There is a Microsoft fix for the EXE/Notepad problem, which I have tried, but it does not resolve my problem.
My problem is not that EXE files call Notepad, but only these Check for Update links. I am guessing that the Check for Update links on these programs (and perhaps others) is using some other key that is erroneously set.
Does anyone have some idea what Registry key these Check for Updates links are calling, or might anyone have some other idea of how to resolve this problem?
