Troubleshooting Problems Opening DUN Files
Frequent DUN Opening Issues
Trendy Entertainment Dungeon Defenders Disappeared
You encounter an error message such as "%%os%% Can't Open DUN Files" when trying to open your DUN. Usually, this is because you do not have Trendy Entertainment Dungeon Defenders for %%os%% installed. Your operating system cannot associate your DUN with Trendy Entertainment Dungeon Defenders, so double-clicking the file won't work.
Tip: When you have another program installed that you know will open your DUN, you can select it from the other programs listed (see "Show Apps").
Incorrect Trendy Entertainment Dungeon Defenders Version
In some cases, you might have a newer (or older) version of a Dungeon Defenders Saved Game File file that is unsupported by your installed application version. You will need to download a newer version of Trendy Entertainment Dungeon Defenders if you don't have the right version. Your Dungeon Defenders Saved Game File file was probably created by a newer release of Trendy Entertainment Dungeon Defenders than what's currently installed your computer.
Tip: Find clues on the correct software version by right-clicking your DUN file and clicking "Properties".
Ultimately, most of the difficulties opening DUN files are due to having the wrong version of Trendy Entertainment Dungeon Defenders installed.
