31. After installing an update patch for one of the Video Guitar Lessons, I get an MMPLAY32.DLL error when trying to launch the program.

Applies to: Essential Rock Guitar Volumes 1 & 2, Essential Blues Guitar Volumes 1 & 2, and Essential Jazz Guitar Volumes 1, 2, & 3.

  • Windows 2000/XP error: "The application has failed to start because MMPLAY32.dll was not found."

  • Windows 98/ME error: "A required .DLL file, MMPLAY32.DLL, was not found."

This means that either (1) you didn't have the full program installed before installing the update patch, or (2) you did have the program installed, but you installed the update patch into the wrong directory.

For (1), the solution is to install the program from the original CD (or the installer that you downloaded if you purchased the program by download-only) and then install the update patch, making sure that they are both installed into C:\BB.

For (2), the solution is simply to run the update installer again, and make sure to specify the correct installation directory. When you installed the program originally, it would have been installed to your Band-in-a-Box® folder by default (ie, C:\BB). Make sure that when you get to the screen that asks you to select the destination directory, it says "C:\BB" (without the quotes), and nothing else.

More information:

The file MMPLAY32.DLL is required for the program to run, and would have been installed when you originally installed the program on your computer. MMPLAY32.DLL must be located in the same folder as the application file. The update patch doesn't install this file or most of the other program files. The fact that you get an MMPLAY32.DLL error would usually indicate that many other program files are missing from the directory.
