Understanding DGML Issues
Common Problems Opening DGML Files
Microsoft Visual Studio Not Present
Double-clicking your DGML file prompts the message "%%os%% Can't Open DGML File". Customarily, this means that Microsoft Visual Studio is not installed on %%os%%. Your operating system cannot associate your DGML with Microsoft Visual Studio, so double-clicking the file won't work.
Tip: If you know of another program that can open your DGML file, you can try opening it by selecting the application from the programs listed.
Microsoft Visual Studio Requires Update
Your Visual Studio Directed Graph Document file is incompatible with Microsoft Visual Studio because you might have the wrong version installed. If you've got the wrong version of Microsoft Visual Studio 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: If you right-click on your DGML file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.
Regardless, most of the DGML file opening problems relate to not having the right version of Microsoft Visual Studio installed.
Other DGML File Opening Causes
Assuming you have the right Microsoft Visual Studio version installed, other problems can prevent you from opening DGML files. Other DGML opening errors can be created by other system problems inside of %%os%%. These issues include:
- Windows Registry DGML file paths that are incorrect
- Corruption of the DGML file description inside the Registry
- Invalid installation of a DGML-associated program (eg. Microsoft Visual Studio)
- Something has caused file corruption of your DGML
- Your DGML is infected with malware
- Hardware associated with DGML has outdated drivers
- Windows cannot load your Visual Studio Directed Graph Document file due to insufficient resources (eg. RAM)
