I started up my PC, running win7 Pro 64bits and I got error message that says:

c:\windows\system32\mscomct2.ocx

unable to register the dll/ocx: regsvr32 failed with exit code 0x3

I did not install any software recently.

I clicked "OK" and then got this error:

c:\windows\system32\msmapi32.ocx

unable to register the dll/ocx: regsvr32 failed with exit code 0x3

Any help to identify root cause and solve this situation?

Thank you

If you are on a 64 bit machine, you need to copy the MSCOMCT2.OCX file to c:\windows\sysWOW64... You then can register it by running from the command prompt or run in the start menu regsvr32 c:\windows\sysWOW64\mscomct2.ocx and it should register although make sure that you run regsvr32 with administrator privileges.

How to run that command in Administrative Mode

================================

1. Click the Start button, then in the "Start Search" box, type CMD but DO NOT press Enter yet.

2. In the list above, under "Programs" right-click on CMD that appears above and choose "Run as Administrator" and click "Continue".

3. In the open window, type the following command and press Enter:

regsvr32 c:\windows\sysWOW64\mscomct2.ocx
