EDIT: I FIXED THE PROBLEM. Apparently I should've repaired the 2015-2019 Windows C++ instead of the suggested 2014 one. Maybe the article was just outdated.
I am using Vegas Movie Studio 17 Platinum - Steam Edition. I have an Intel i7-7700HQ CPU on a Windows 10 computer.
Side note: I've already followed [https://steamcommunity.com/sharedfiles/filedetails/?id=518954593] this tutorial to no avail, from start to end, and am now at a loss.
Every time I try to launch MS17P-SE from Steam, I get an error message stating that the movie studio executable file cannot be found. This is not the main issue though, because I can bypass this by going into the Steam files and running the installer manually, and changing the opening destination to the proper folder (I do want this problem fixed too though, and I have provided the log file for this problem at the bottom). When I do this, it loads for a little while longer, and sends me an error that says the same exact thing as the one on the link provided under its "I got an error message while running the installer" section, under "Technical error messages". Since I've followed that other tutorial, I have no idea where to go from here, as that was the most extensive tutorial to fix my problem that I've found thus far. I understand it was for MS13, but it was still useful, as it pertained to all of my issues (but sadly were not fixed).
Anything else I'm not doing, and anyone else suffering from this?
