Troubleshoot JLB Files

Common Problems Opening JLB Files

Windows Mobile Disappeared

When trying to open your JLB file, you get the error "Can't Open JLB File Type". Generally, this is experienced in %%os%% because Windows Mobile isn't installed on your PC. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you know of another program that can open your JLB file, you can try opening it by selecting the application from the programs listed.

Outdated Windows Mobile

Sometimes your installed version of Windows Mobile won't support your PAC Mate BX Keyboard Driver file. If you've got the wrong version of Windows Mobile installed, you'll need to install the correct version. Most of the time your PAC Mate BX Keyboard Driver file was created by a newer Windows Mobile than what you have installed.

Tip: Find clues on the correct software version by right-clicking your JLB file and clicking "Properties".

Ultimately, most of the difficulties opening JLB files are due to having the wrong version of Windows Mobile installed.
