2. Start-Up Issues Issues

2a.   I receive a Runtime 339 Error telling me that the component MSCOMCT2.OCX is missing.

Runtime Error 339 occurs if the ActiveX component MSCOMCT2.OCX is missing from your Windows installation (it should be part of Windows but in many cases the file is not installed). You can solve this problem by downloading the file MSCOMCT2.OCX from our website, by copying it to the \system32 folder of your Windows installation (or the \sysWOW64 folder of your 64-bit Windows Vista installation) and by registering it.

1. Download the file from here.

2. Place the file in the \system32 directory/folder of your Windows installation (\sysWOW64 folder of your 64-bit Vista installation).

3. Register the file as follows:

a. Click the Windows Start button

b. Click on Run

c. In the "Open" field type, exactly as it appears here, as applicable:
regsvr32 \windows\system32\MSCOMCT2.OCX
regsvr32 \windows\sysWOW64\MSCOMCT2.OCX

Note: If your Windows installation folder is not called windows, type the name of your Windows installation folder in place of windows in the above command

After you run the command, you should see the message


If you don't see this message, you've not typed the command exactly as written above (your best bet is probably to cut and paste it from here) or you've not placed the file in the correct location, so try again. Note that there is a SPACE between regsvr32 and \windows/system32\MSCOMCT2.OCX
