Troubles Opening AUX Files
Missing MiKTeX
You encounter an error message such as "%%os%% Can't Open AUX Files" when trying to open your AUX. If so, it typically means that you don't have MiKTeX installed for %%os%%. You won't be able to double-click to open your AUX because your OS doesn't know what to do with it.
Tip: When you have another program installed that you know will open your AUX, you can select it from the other programs listed (see "Show Apps").
Obsolete Version of MiKTeX
Occasionally, you might have an outdated version of MiKTeX installed that's incompatible with your LaTeX Auxiliary File type. If you do not have the proper version MiKTeX (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is predominately due to having a LaTeX Auxiliary File file version that was created by a newer version of MiKTeX than what you have installed on your PC.
Tip: If you right-click on your AUX file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.
Summary: Not having the right MiKTeX version on your computer can cause problems opening AUX files.
Other Causes of AUX File Opening Problems
You can still experience errors opening AUX files even with the latest version of MiKTeX installed on your PC. Other AUX opening errors can be created by other system problems inside of %%os%%. These other problems include (listed in order from most to least common):
- Corrupt Windows Registry file path references for AUX
- Mistaken removal of the Windows registry AUX description
- MiKTeX or another AUX application experienced a flawed installation
- The AUX itself is corrupted
- Malware-tainted AUX file can't be opened
- Hardware associated with AUX has outdated drivers
- Your PC doesn’t have enough available resources to open the LaTeX Auxiliary File file
