SYMPTOMS

When you try to start a program that supports the Telephony Application Programming Interface (TAPI), you may receive the following error message:

Error Starting Program

The TAPI32.DLL file cannot start. Check the file to determine the problem.

CAUSE

The TOOLHELP.DLL file is missing or damaged, or has been replaced by another program. The TOOLHELP.DLL file should be located in the Windows\System folder.

RESOLUTION

Use the EXTRACT command to replace the TOOLHELP.DLL file. To extract the file, use the following command

   extract /l <drive letter>:\<windows>\system <filename.cab> toolhelp.dll

where <drive letter> indicates the letter designating the drive containing the Windows 95 floppy disk or CD-ROM, <windows> is the Windows 95 folder, and <filename.cab> is the name of the cabinet file containing the TOOLHELP.DLL file. For example,

From disk 4:

   extract /l c:\windows\system win95_04.cab toolhelp.dll

From the Windows 95 CD-ROM:

   extract /l c:\windows\system win95_03.cab toolhelp.dll

For information about using the EXTRACT command, type

extract /?

at a command prompt.
