Understanding 90 Issues

Common Problems Opening 90 Files

Pro/ENGINEER is Not Installed

When you double-click your 90 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If so, it typically means that you don't have Pro/ENGINEER installed for %%os%%. This will prevent you from double-clicking to open the 90 file because the OS doesn’t know how to handle it.

Tip: When another 90 application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Pro/ENGINEER Requires Update

In some cases, you might have a newer (or older) version of a Creo Elements/Pro Versioned Data file that is unsupported by your installed application version. You will need to download a newer version of Pro/ENGINEER if you don't have the right version. 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: You can sometimes get hints about the right program version by right-clicking on the 90 file, selecting "Properties", and looking at the version information.

Summary: Not having the right Pro/ENGINEER version on your computer can cause problems opening 90 files.

Other 90 File Issues

Even with the correct version of Pro/ENGINEER installed, you can still experience difficulties opening 90s. If you are still having problems opening 90 files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

• File references in the Windows Registry for 90 are wrong
• The 90 file description within the Windows Registry was removed
• Partial installation of Pro/ENGINEER that did not fully complete
• Something has caused file corruption of your 90
• Your 90 has adversely impacted by malware
• Drivers associated with 90 software need to be updated
• Your computer does not have the adequate system resources to open the Creo Elements/Pro Versioned Data format
