Troubleshooting Problems Opening OP Files

Issues Opening OP Files

OpenPAT Disappeared

When you double-click your OP file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have OpenPAT for %%os%% installed. The OS won't know what to do with your OP file, so double-clicking to load the file doesn't work.

Tip: If you have another software that you know opens OP files, you can select it by hitting the "Show Apps" button.

Outdated OpenPAT

Occasionally, you might have an outdated version of OpenPAT installed that's incompatible with your OpenPAT Report type. Download the latest OpenPAT version from the Open Source website to ensure you have the correct one installed. This issue mainly occurs when your OpenPAT Report file was created by a newer version of OpenPAT than you have on your PC.

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

Summary: Not having the right OpenPAT version on your computer can cause problems opening OP files.

• The OP itself is corrupted
• The OP is infected with a virus
• Hardware associated with OP has outdated drivers
