Troubleshooting Problems Opening 26 Files

Troubles Opening 26 Files

Pro/ENGINEER Disappeared

When trying to open your 26 file, you get the error "Can't Open 26 File Type". Generally, this is experienced in %%os%% because Pro/ENGINEER isn't installed on your PC. You won't be able to double-click to open your 26 because your OS doesn't know what to do with it.

Tip: If you know of another program that can open your 26 file, you can try opening it by selecting the application from the programs listed.

Pro/ENGINEER is Out-of-Date

Sometimes your installed version of Pro/ENGINEER won't support your Creo Elements/Pro Versioned Data file. Visit the PTC website to download (or purchase) the latest version of Pro/ENGINEER. 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: If you right-click on your 26 file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: Not having the right Pro/ENGINEER version on your computer can cause problems opening 26 files.

Additional 26 Opening Issues

Even with the correct version of Pro/ENGINEER installed, you can still experience difficulties opening 26s. There can be external issues inside of %%os%% that are causing these errors when opening 26s. Other contributing causes:

• Windows Registry 26 file paths that are incorrect
• Mistaken removal of the Windows registry 26 description
• Corrupt install of Pro/ENGINEER or other 26-related program
• Your 26 file is corrupted (issues with your Creo Elements/Pro Versioned Data file itself)
• The 26 is infected with a virus
• Drivers associated with 26 software need to be updated
• Windows cannot load your Creo Elements/Pro Versioned Data file due to insufficient resources (eg. RAM)
