Run a dLL !

I am not sure of what I did, but wherever I try to open add/remove programs in control panel, it gives me a run a dLL error. I tried system scan by many antiviruses and even system restore but still the same issue. How can I fix it
Answer #1
Is this a d11 error or .DLL error? If it’s a .dll file it may be missing. If this is the case run your CMD (command line) and type regsvr32 mshtml.dll
regsvr32 shdocvw.dll -I
regsvr32 shell32.dll -I
If this does not work you may need to look deeper into the issue.
