Troubleshoot WPJ Files

Common Problems Opening WPJ Files

Watcom C/C++ is Not Installed

Double-clicking your WPJ file prompts the message "%%os%% Can't Open WPJ File". Customarily, this means that Watcom C/C++ is not installed on %%os%%. Your operating system cannot associate your WPJ with Watcom C/C++, so double-clicking the file won't work.

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

Outdated Watcom C/C++

In some cases, you might have a newer (or older) version of a Watcom C/C++ Project file that is unsupported by your installed application version. If you've got the wrong version of Watcom C/C++ installed, you'll need to install the correct version. The primary cause of this problem is that your Watcom C/C++ Project file was created by a different (newer) version of Watcom C/C++ than what's installed.

Tip: Right-clicking on your WPJ, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.

Summary: Not having the right Watcom C/C++ version on your computer can cause problems opening WPJ files.
