Understanding PGM Issues
Frequent PGM Opening Issues
Adobe Photoshop Not Present
Double-clicking your PGM file prompts the message "%%os%% Can't Open PGM File". Customarily, this means that Adobe Photoshop is not installed on %%os%%. Your operating system cannot associate your PGM with Adobe Photoshop, so double-clicking the file won't work.
Tip: Another PGM-related program can be selected to open the file by clicking "Show Apps" and finding the application.
Incorrect Adobe Photoshop Version
In other instances, your Portable Gray Map Image file version may not be supported by your version of Adobe Photoshop. If you've got the wrong version of Adobe Photoshop installed, you'll need to install the correct version. Most of the time your Portable Gray Map Image file was created by a newer Adobe Photoshop than what you have installed.
Tip: If you right-click on your PGM file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.
Ultimately, most of the difficulties opening PGM files are due to having the wrong version of Adobe Photoshop installed.
Additional PGM Opening Issues
Assuming you have the right Adobe Photoshop version installed, other problems can prevent you from opening PGM files. If you are continuing to have errors with loading PGM files, other external issues might be to blame. Problems unrelated to software:
- Corrupt Windows Registry file path references for PGM
- Mistaken removal of the Windows registry PGM description
- Partial installation of Adobe Photoshop that did not fully complete
- File corruption affecting your PGM file
- Your PGM is infected with malware
- PGM-related hardware has device drivers that obsolete
- Too many applications are open on your PC to load your Portable Gray Map Image file successfully
