BKS Troubleshooting

Issues Opening BKS Files

Microsoft Windows NT Backup - Restore Utility Isn't There

If you attempt to load your BKS file, you experience a message such as "Can't Open BKS Files". If this is the case, it's usually due to the fact that you do not have Microsoft Windows NT Backup - Restore Utility for %%os%% installed on your computer. The OS won't know what to do with your BKS file, so double-clicking to load the file doesn't work.

Tip: If you have another software that you know opens BKS files, you can select it by hitting the "Show Apps" button.

Microsoft Windows NT Backup - Restore Utility is Out-of-Date

In some cases, you might have a newer (or older) version of a NTBackup Settings File file that is unsupported by your installed application version. Installing the latest version of Microsoft Windows NT Backup - Restore Utility from Microsoft Corporation is recommended. Most of the time your NTBackup Settings File file was created by a newer Microsoft Windows NT Backup - Restore Utility than what you have installed.

Tip: Investigate your BKS file by right-clicking and selecting "Properties" to find clues on what version you need.

Summary: Not having the right Microsoft Windows NT Backup - Restore Utility version on your computer can cause problems opening BKS files.

Other BKS File Issues

In the majority of cases, installing the right version of Microsoft Windows NT Backup - Restore Utility will resolve your issue. If you're still experiencing problems opening BKS files, there could be other computer problems. Additional factors include:

• Corrupt Windows Registry file path references for BKS
• The BKS file description within the Windows Registry was removed
• Incomplete or bad installation of a software application associated with the BKS format
• Your BKS can't be loaded properly (file corruption)
• The BKS is infected with a virus
• Drivers associated with BKS software need to be updated
• Too many applications are open on your PC to load your NTBackup Settings File file successfully
