Collection of .OCX and .sys files
You may download just the file you are missing and manually register it yourself. Here's how to do it:
Back up your current copy of MSCOMCTL.OCX and copy the new version to the same file location. This file should be located in the WINDOWS\SYSTEM directory on your C: drive (for Windows NT and 2000: \WINNT\system32).
Using your mouse, click on the "Start" button and then click on "Run".
According to your Operating System, type the following command to register this library file:
Windows 95, 98, or Me:
Windows NT or 2000:
You should see a message saying "DllRegisterServer ... succeeded"
If you are getting an error telling you that the file is missing, then you are not typing the command in correctly. You will need to type it in *exactly* as as shown above for your operating system.
* Please note that there is a SPACE after "regsvr32" and before the rest of the command.
You should probably copy and paste the command so that you are unable to mistype it.
