.exe program files opening with Microsoft word by default

Hello,

I recently ran into an issue where this installation on Windows 7 Pro 32-bit is trying to open up all my programs in Word, they all have the MS word icon as well, so for instance, when I click on Nero, it will try to open it up in word and we get an error because it is not a word file. This is on all Program .exe files. There are no options to change the file association in the default programs in control panel. I have only seen a few fixes for this which involve the registry, I have checked these, however, all registry keys are correct. System restore fails as well, have tried multiple restore points to no avail. We have also ran norton, and malwarebytes on the system is it runs clean. I am not sure where to go from here. Any input would be appreciated. Thanks.

Thank you for your response, Brink. However, I have already attempted this fix and it did not work. I then tried to manually enter all of the registry data, but it did not resolve the issue. Any other thoughts would be helpful. Thanks.

I have actually already tried that as well...
