Troubleshoot XLB Files
Common XLB Opening Problems
Microsoft Excel Not Present
You attempt to load your XLB file and get an error such as "%%os%% Can't Open The XLB File Extension". If this is the case, it's usually due to the fact that you do not have Microsoft Excel for %%os%% installed on your computer. The OS won't know what to do with your XLB file, so double-clicking to load the file doesn't work.
Tip: When another XLB application is installed, you can choose to open it by selecting "Show Apps" and using that program.
Incorrect Microsoft Excel Version
Sometimes your installed version of Microsoft Excel won't support your Excel Toolbars File file. Download the latest Microsoft Excel version from the Microsoft Corporation website to ensure you have the correct one installed. The primary cause of this problem is that your Excel Toolbars File file was created by a different (newer) version of Microsoft Excel than what's installed.
Tip: Investigate your XLB file by right-clicking and selecting "Properties" to find clues on what version you need.
Summary: In either case, the majority of problems opening XLB files are related to not having the correct software application installed on your computer.
Other XLB File Issues
You can still experience errors opening XLB files even with the latest version of Microsoft Excel installed on your PC. Other XLB opening errors can be created by other system problems inside of %%os%%. Problems unrelated to software:
- Windows Registry XLB file paths that are incorrect
- The XLB file description within the Windows Registry was removed
- Incomplete or bad installation of a software application associated with the XLB format
- The XLB itself is corrupted
- Your XLB is infected with malware
- Hardware related to XLBs has device driver corruption
- Your PC doesn’t have enough available resources to open the Excel Toolbars File file
