Sources of RU Problems

Frequent RU Opening Issues

Microsoft Notepad Disappeared

You attempt to load your RU file and get an error such as "%%os%% Can't Open The RU File Extension". If this is the case, it's usually due to the fact that you do not have Microsoft Notepad for %%os%% installed on your computer. Your operating system cannot associate your RU with Microsoft Notepad, so double-clicking the file won't work.

Tip: Another RU-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Obsolete Version of Microsoft Notepad

In other instances, your Russian Text Or Localization 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 problem is predominately due to having a Russian Text Or Localization File file version that was created by a newer version of Microsoft Notepad than what you have installed on your PC.

Tip: You can sometimes get hints about the right program version by right-clicking on the RU file, selecting "Properties", and looking at the version information.

Primarily, problems experienced when opening RU files are due to having the incorrect version of Microsoft Notepad installed on your computer.

Additional RU Opening Issues

Although you might already have Microsoft Notepad or another RU-associated software installed on your computer, you can still encounter problems opening Russian Text Or Localization File files. Other RU opening errors can be created by other system problems inside of %%os%%. Problems unrelated to software:

• Invalid RU file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Accidental deletion of the description of the RU file in the Windows registry
• Defective install of a RU program, such as Microsoft Notepad
• RU file corruption
• Malware-tainted RU file can't be opened
• Device drivers for RU-related hardware are out-of-date
• Your PC doesn’t have enough available resources to open the Russian Text Or Localization File file
