SYMPTOMS

When you use Visual Studio .NET with the MERANT PVCS Version Manager, you may receive the following error message:
Unhandled exception has been caught by the Visual Studio Watson exception filter
The exception occurs in the Ifc_com.dll module. Alternatively, when you use the Recalculate Hyperlinks operation in Visual InterDev or FrontPage, the system stops responding (hangs).

If you use a debugger such as Dr. Watson, the beginning of the call stack appears as follows: 

IFC_COM.DLL+0x29b2

CAUSE

This problem occurs because the Ifc_com.dll module is a MERANT dynamic-link library (DLL) and is installed with the PVCS source control product.

RESOLUTION

Although you can unregister this DLL to prevent this crash from occurring, you may experience unexpected results in the MERANT product if you unregister this DLL. Microsoft recommends that you contact MERANT to resolve this problem. For MERANT contact information, see the "More Information" section.

To unregister the Ifc_com.dll file, click Start, click Run, and then type the following command in the Open box:

regsvr32 /u drive letter:\path\ifc_com.dll

where drive letter and path are the drive and the path of the Ifc_com.dll file.

To register the Ifc_com.dll file, use the following command:

regsvr32 drive letter:\path\ifc_com.dll

MORE INFORMATION

You do not have to examine the call stack dump file to use this article. If you experience an unhandled exception when you use Visual Studio .NET, or if the system stops responding when you use FrontPage or Visual InterDev, and if you have MERANT PVCS Version Manager, you may want to use the resolution.
