I'm a novice PreTeXt user, trying to get my PC set up and I've come across an issue while trying to compile to pdf. I get a fatal format error message and when I open the MikTeX console, it says there is a PATH issue. The message says "This directory is not in the search list for executables or it is at the wrong position in the list. You can fix this issue by adding the directory to the environment variable PATH. This makes it possible to invoke the MikTeX executables anywhere."
However, I have Windows 10 and I'm hesitant to change any PATH environment variables, after reading the caution given in Jessica Sklar's tutorial.
Is it safe to change this PATH environment variable? If so, exactly how do I do that?
Thanks!
