Error and Solution:
Error:
Application folder:
C:/Users/[username]/AppData/Roaming/itch/apps/digital-logic-sim2/Widows
There should be 'DigitalLogicSim_Data'
folder next to the executable
Solution:
Rename the file "Digital Logic Sim_Data" to "DigitalLogicSim_Data" that's all it takes, and I got it working after renaming the file.
