UMB File Complications
Troubles Opening UMB Files
MS-DOS Isn't There
Double-clicking your UMB file prompts the message "%%os%% Can't Open UMB File". If so, it typically means that you don't have MS-DOS installed for %%os%%. Your operating system cannot associate your UMB with MS-DOS, so double-clicking the file won't work.
Tip: When another UMB application is installed, you can choose to open it by selecting "Show Apps" and using that program.
MS-DOS is Out-of-Date
In some cases, you might have a newer (or older) version of a MemMaker Backup Archive file that is unsupported by your installed application version. Visit the Microsoft Corporation website to download (or purchase) the latest version of MS-DOS. Most of the time your MemMaker Backup Archive file was created by a newer MS-DOS than what you have installed.
Tip: Right-clicking on your UMB, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Summary: Not having the right MS-DOS version on your computer can cause problems opening UMB files.
Other Causes of UMB File Opening Problems
Errors opening MemMaker Backup Archive files can still occur even with the latest MS-DOS software installed on your computer. If you are continuing to have errors with loading UMB files, other external issues might be to blame. These other problems include (listed in order from most to least common):
- Corrupt Windows Registry file path references for UMB
- Unintentional removal of the description of the UMB file inside the Windows Registry
- Invalid installation of a UMB-associated program (eg. MS-DOS)
- Your UMB file is corrupted (issues with your MemMaker Backup Archive file itself)
- Your UMB is infected with malware
- Device drivers of the hardware associated with your UMB file are corrupt or out-of-date
- Your computer does not have the adequate system resources to open the MemMaker Backup Archive format
