Troubles Opening USER Files

Microsoft Notepad Isn't There

You encounter an error message such as "%%os%% Can't Open USER Files" when trying to open your USER. Usually, this is because you do not have Microsoft Notepad for %%os%% installed. Your operating system cannot associate your USER with Microsoft Notepad, so double-clicking the file won't work.

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

Microsoft Notepad Requires Update

In other instances, your Visual Studio Project User Options File file version may not be supported by your version of Microsoft Notepad. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Notepad. This issue mainly occurs when your Visual Studio Project User Options File file was created by a newer version of Microsoft Notepad than you have on your PC.

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

Summary: In either case, the majority of problems opening USER files are related to not having the correct software application installed on your computer.

Other Causes of USER File Opening Problems

Even with the correct version of Microsoft Notepad installed, you can still experience difficulties opening USERs. If you're still experiencing problems opening USER files, there could be other computer problems. Problems unrelated to software:

• Accidental deletion of the description of the USER file in the Windows registry
• Invalid installation of a USER-associated program (eg. Microsoft Notepad)
• Your USER can't be loaded properly (file corruption)
• The USER is infected with a virus
• Device drivers for USER-related hardware are out-of-date
