177. Error message when loading the program: "System cannot find file specified at..."

This is most likely a Windows error that occurs when Band-in-a-Box® asks Windows to search for DirectX plugins on your computer. The problem is probably related to an incorrectly installed or corrupt DirectX Plugin.

To fix this, you should first eliminate the possibility that there is a problem with one of the Band-in-a-Box® settings files, or one of the PG Music DirectX plugins. To do this, perform an install of the main program to a different folder than it's installed to now. This won't "mess up" your existing installation. Just choose a different Band-in-a-Box® folder, for example C:\bb_test. You don't need to reinstall RealTracks files, but in the Setup wizard make sure that the PG DirectX plugins component is selected. Once it's finished, run Band-in-a-Box® from the new folder and see if the same error occurs. If it doesn't, you could use your new installation, or you may be able to fix your old installation by returning the program to factory settings as in this FAQ topic (delete the dxplugin related files listed there).

If the error still occurs with the new installation, then here are some further tips.

  • Try downloading the latest version of DirectX from Microsoft's website.

  • Check your hard disk for errors. Right Click on your hard drive and select Properties. On the Tools tab - Error Checking, click the Check Now button. Check both boxes (Fix File System Errors and Scan/attempt recovery of bad sectors). You will need to reboot the computer to run this scan.

As mentioned, if none of those suggestions fixed the problem, there is most likely a third party (non-PG Music) DirectX plugin on your computer which was moved or deleted, or there is a problem with the plugin's registry entry. It is possible that just one corrupt DX plugin file somewhere on your computer is causing the problem

  • If you have recently installed any third party DirectX plugins (or software that might have included DX plugins), try uninstalling/reinstalling this software.

  • In the Band-in-a-Box® folder (e.g. C:\bb\Data\Logs) you should find a file called PluginScanLog.log. This file can be opened with a text editor like NotePad. Since this file will be recently modified, if you sort the contents of the bb folder by date modified, you'll be able to find it easily. This file may tell you which plugin is causing the problem by seeing if there's a particular plugin that the log stops at. Then you can either try to fix the plugin (uninstall/reinstall/clean it out of registry) or add it to the Band-in-a-Box® DX plugin exclude list.

    The exclude list is also found in the bb\Preferences folder - called "dxplugexclude.ini". This file can be edited with NotePad. Save a backup copy of the original "factory" file, so you can revert back to it if needed. If you add a plugin to the list, launch Band-in-a-Box® and see if you still get the error. If you do, examine the PluginScanLog again, repeating this for any other plugins it stops at.

  • You could try to track down and uninstall all of your plugins. You may also be able to find a utility that will check the registry and flag any DX plugin that has a registry entry which no longer points to a valid file.

Alyssa, I think this FAQ needs to be updated for new file locations in BIAB 2018 and 2019.

PluginScanLog.log is now located in /bb/Data/Logs

dxplugexclude.ini is now located in /bb/Preferences

The Band-in-a-Box® Flash Drive Backup Option

For the larger Band-in-a-Box® packages (UltraPAK, UltraPAK+, Audiophile Edition), the hard drive backup copy is available for only $25. This will include a preinstalled and ready to use program, along with your installation files.

Backup copies are offered during the checkout process on our website.

Handy flash drive tip: Always try plugging in a USB device the wrong way first? If your flash drive (or other USB plug) doesn't have a symbol to indicate which way is up, look for the side with a seam on the metal connector (it only has a line across one side) - that's the side that either faces down or to the left, depending on your port placement.

Band-in-a-Box® 2024 Review: 4.75 out of 5 Stars!

If you're looking for a in-depth review of the newest Band-in-a-Box® 2024 for Windows version, you'll definitely find it with Sound-Guy's latest review, Band-in-a-Box® 2024 for Windows Review: Incredible new capabilities to experiment, compose, arrange and mix songs.

A few excerpts:
"The Tracks view is possibly the single most powerful addition in 2024 and opens up a new way to edit and generate accompaniments. Combined with the new MultiPicker Library Window, it makes BIAB nearly perfect as an 'intelligent' composer/arranger program."

"MIDI SuperTracks partial generation showing six variations – each time the section is generated it can be instantly auditioned, re-generated or backed out to a previous generation – and you can do this with any track type. This is MAJOR! This takes musical experimentation and honing an arrangement to a new level, and faster than ever."

"Band in a Box continues to be an expansive musical tool-set for both novice and experienced musicians to experiment, compose, arrange and mix songs, as well as an extensive educational resource. It is huge, with hundreds of functions, more than any one person is likely to ever use. Yet, so is any DAW that I have used. BIAB can do some things that no DAW does, and this year BIAB has more DAW-like functions than ever."
