Hiya guys.
So while preparing Snares of Ruin Zero for release, I've managed to find out what's going on with launch problems that some people have been experiencing.
As I mentioned in some discussion threads before, there is a third party program called Node js (Nwjs) that is required as a launcher for this game (and other more recent games of mine: Pegasus-5, Snares of Ruin, Renegade Grounds, and will also be for Snares of Ruin Zero). This program together with one of the plugins is required for integration of Steam achievements. Unfortunately from what I've been testing today, the newer versions of Node js give a lot of problems and often don't trigger achievements (possibly due to conflicts with other plugins). So, as of right now, staying with version 22.3 of Node js is the best bet to make sure achievements still trigger.
However, if the computer has used a newer version of Node js for running of other games, then it could cause launch problems of games that used older version of Node js. There is a handy fix that can allow you to stop this from happening.
You have to go to the following folder:
C:\Users\(your username here)\AppData\Local\KADOKAWA\RPGMV\UserData\Default
And then scroll all the way down and locate two files:
"Web Data" and "Web Data-journal", and DELETE them.
This will stop the override and will allow your computer to run games that use any version of Node js that's older than the whichever is the newest version you used.
If you happen to run a game later that uses a newer version of Node js, then you might have to do this fix again as the "Web Data" and "Web Data-journal" files will reappear and constantly auto-update based on what version of Node js you've been using.
Just a note - AppData folder is normally hidden on your computer, so you'll first have to 'show hidden folders' from your computer's Control Panel.
I hope this helps, and please feel free to ask any questions if you're still stuck.
The alternative solution that was mentioned before is to launch the game via Firefox browser (by going into game folders and launching it through the file called 'index').
