Instructions for replacing MSCOMCTL.OCX

To properly replace your missing MSCOMCTL.OCX file please use the following instructions:

  1. Download MSCOMCTL.OCX (right click the text on the left and save to your Desktop).
  2. 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).
  3. Using your mouse, click on the “Start” button and then click on “Run”.
  4. According to your Operating System, type the following command to register this library file:

    Windows 95, 98, or Me:
    regsvr32 \windows\system\MSCOMCTL.OCX

    Windows NT or 2000:
    regsvr32 \WINNT\system32\MSCOMCTL.OCX

    Windows XP:
    regsvr32 \windows\system32\MSCOMCTL.OCX
  5. 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.
