I have a VB project was able to work without any issues, but now when i open the project i am getting the error with mscomctl.ocx. I have re-registered the ocx but still am not
Try re-registering MSCOMCTL.OCX:
MSCOMCTL.OCX
c:\windows\system32\
open command prompt and run this:
cd c:\windows\system32 regsvr32 MSCOMCTL.OCX
Than try to run your application again.
