PC Forms: Errors When Opening E-Forms Under Windows NT

• Microsoft Electronic Forms Designer, version 1.0, running with Microsoft Mail for PC Networks, version 3.0 or 3.2

SYMPTOMS

When you choose an E-form that was created using version 1.0 of the Microsoft Electronic Forms Designer from the Browser application, you may receive one of the following error messages:

   Another machine is already signed in with the username you have
   entered. Sign out from the other machine and try again.

   MAPI_FAILURE

CAUSE

The above errors may appear if you open the custom form from version 3.0 or 3.2 of the 16-bit Microsoft Mail for Windows client running under the Microsoft Windows NT operating system. If the 16-bit MAPI.DLL file is not located in the WINNT\SYSTEM32 directory, the search path will find the 32-bit MAPI.DLL file in that directory and will attempt to open a second MAPI session.

RESOLUTION

To resolve this problem, copy the MAPI.DLL file from the WINNT\SYSTEM directory to the WINNT\SYSTEM32 directory. When an E-form is launched, it will find the 16-bit version of MAPI.DLL, which is the one that is used by the 16-bit Mail client.
