Troubleshoot GMP Files

Common GMP Opening Problems

Global Mapper Not Present

When trying to open your GMP file, you get the error "Can't Open GMP File Type". Customarily, this means that Global Mapper is not installed on %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: When you have another program installed that you know will open your GMP, you can select it from the other programs listed (see "Show Apps").

Global Mapper Requires Update

Sometimes your installed version of Global Mapper won't support your Global Mapper Package File file. If you've got the wrong version of Global Mapper installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.

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

Regardless, most of the GMP file opening problems relate to not having the right version of Global Mapper installed.

Other GMP File Opening Causes

In the majority of cases, installing the right version of Global Mapper will resolve your issue. If you are still having problems opening GMP files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

• Corrupt Windows Registry file path references for GMP
• Unintentional removal of the description of the GMP file inside the Windows Registry
• Partial installation of Global Mapper that did not fully complete
• GMP file corruption
• Your GMP has adversely impacted by malware
• GMP-related hardware has device drivers that obsolete
• Too many applications are open on your PC to load your Global Mapper Package File file successfully
