Troubleshooting Problems Opening OL Files

Frequent OL Opening Issues

Valve Hammer Editor Removed

When trying to open your OL file, you get the error "Can't Open OL File Type". Generally, this is experienced in %%os%% because Valve Hammer Editor isn't installed on your PC. Your operating system cannot associate your OL with Valve Hammer Editor, so double-clicking the file won't work.

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

Valve Hammer Editor Requires Update

In some cases, you might have a newer (or older) version of a Valve Hammer Object Layout File file that is unsupported by your installed application version. If you do not have the proper version Valve Hammer Editor (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 predominately due to having a Valve Hammer Object Layout File file version that was created by a newer version of Valve Hammer Editor than what you have installed on your PC.

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

Ultimately, most of the difficulties opening OL files are due to having the wrong version of Valve Hammer Editor installed.
