Troubleshooting Problems Opening GMMP Files

Troubles Opening GMMP Files

Microsoft Windows Isn't There

When you double-click your GMMP file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Microsoft Windows missing in %%os%%. The OS won't know what to do with your GMMP file, so double-clicking to load the file doesn't work.

Tip: If you don't have Microsoft Windows installed, and you know of another program to open your GMMP file, you can try opening it by selecting from the programs listed under "Show Apps".

Outdated Microsoft Windows

Sometimes your installed version of Microsoft Windows won't support your WCS Gamut Map Model Profile file. If you've got the wrong version of Microsoft Windows installed, you'll need to install the correct version. Your WCS Gamut Map Model Profile file was probably created by a newer release of Microsoft Windows than what's currently installed your computer.

Tip: Investigate your GMMP file by right-clicking and selecting "Properties" to find clues on what version you need.

Conclusion: The majority of GMMP file opening issues are due to not having the correct Microsoft Windows version installed.
