Troubleshooting Problems Opening YANG Files

Common Problems Opening YANG Files

Visual YANG Designer is Not Installed

When you double-click your YANG file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If this is the case, it's usually due to the fact that you do not have Visual YANG Designer for %%os%% installed on your computer. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

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

Wrong Version of Visual YANG Designer is Installed

In some cases, you might have a newer (or older) version of a YumaPro file that is unsupported by your installed application version. If you do not have the proper version Visual YANG Designer (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

Tip: Sometimes you can get a clue about the version of YANG file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

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

Other Causes of YANG File Opening Problems

• Invalid YANG file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Accidental deletion of the description of the YANG file in the Windows registry
• Incomplete or bad installation of a software application associated with the YANG format
• Your YANG file is corrupted (issues with your YumaPro file itself)
• Your YANG is infected with malware
• Device drivers of the hardware associated with your YANG file are corrupt or out-of-date
