FAQ028

Why do I get an Application Error or General Protection Fault (GPF) when I try to mail-merge in Windows NT or 2000?

** This only applies to Professional Investigator v3 or earlier **

which will solve this problem.

When you use Professional Investigator's mail-merge facility with Microsoft Word, Professional Investigator sends commands and data to Word using Object Linking & Embedding (OLE) and Dynamic Data Exchange (DDE).  These two services are provided by your operating system, namely, Windows.

Because Professional Investigator v3 is a 16-bit program, they work fine in Windows 95, 98 and ME, which are hybrid operating systems, offering both 32-bit and 16-bit functionality. Windows NT and Windows 2000 (which is simply the latest version of Windows NT) are 32-bit throughout, and so cannot support services such as OLE and DDE, in a 16-bit environment.

To allow users of Windows NT and Windows 2000 to mail-merge successfully with Microsoft Word, we have written a separate 32-bit mail-merge module.
You should only download this module if you are running Windows NT or Windows 2000, and are experiencing problems.

This module will install into your Professional Investigator folder, and will place a new icon on your desktop, and in the Professional Investigator section of your Windows Start menu.

Note:

    This mail-merge error is entirely separate to the 'wow32' problem described in FAQ029. If you see an error saying, 'PI_MAIN has caused an access violation in WOW32.DLL...' in Windows 2000, please see FAQ029 for more information and a solution.

Addendum:

    Professional Investigator v3.0g and above now checks your Windows version, and will disable the internal mail-merge facility if it detects that you are running under Windows NT or 2000.  This should stop any errors caused by inadvertently using the internal mail-merge rather than this new module.  Click here to download the latest version.
