When I try to open an attachment, I get the error, Class Not Registered. How can I correct this? This just recently started.

Try running the system file checker,see if that fixes it.

 

Open an elevated command prompt ( Open the Start menu, - type cmd to open  search 

Right click  then click Run as Administrator

In the elevated command prompt, type sfc /scannow and press enter

When the scan finishes you should see

 

 Windows Resource Protection did not find any integrity violations 

 

If no issues were found, then close the command prompt.

Hi ^_^,

 

I can't even open my start menu.

What kind of attachments are you trying to open?

 

Also, does pressing the keyboard combination - Windows (Start button) + R , open a RUN dialog box? If yes, then type CMD and follow Wolverine 7's advice.

May I tack onto this or should I create a new thread? My 'Class not registered' message comes when I try to open snips saved in my (PC-based) OneDrive. It started after the Windows Anniversary Update so I'm blaming that although I have no proof!

 

I'll run sfc/ scannow in the meantime. Thanks in anticipation.

sfc/ scannow gave me a clean bill of health - no integrity violations. What should I do next, please?

 

PS sfc/ scannow actually brought up a menu of the options, effectively telling me that the correct elevated command is sfc/ SCANNOW. This is the first time it's said this. What's changed it? PS Because of the blasted 'Class not registered' message I can't post a snip here!!!!
