I'm seeing two conflicting versions in that error - 1.5 and 1.75.
You can safely use the 1.75's version's files, no need to hold onto the 1.5 version's folder/files.
So where do I go to remove it so I can keep playing. Amazing game by the way and thank you for the very fast reply!
Which link did you use here on Itch? If you downloaded the Days 1-16 Endurance Version for PC, you would extract all of those files and find the StrandedInSpace.exe inside and then just double click it.
Alright sweet I'll let you know if it works or if I run into anymore issues, Thank you.
