* When I try to run Aphirm-It, it dies with the following error: Run-time error "339": Component 'mscomctl.ocx' or one of its dependencies not correctly registered: a file is missing or invalid
MSCOMCTL.OCX is a support file required to run Aphirm-It that is already installed on most home computers. It is not included with the main distribution to decrease the download time. If you encounter this error, you will need to download the file called MSCOMCTL.ZIP from the downloads page. Extract the included file MSCOMCTL.OCX into your C:\WINDOWS\SYSTEM directory.
