R executable not found

After uploading to the folders everything said and changing all names to my app name, it finds an issue where it tries to open a different disk from the one the app is in.
When I click on the .bat file, Windows Script host says "Error: R executable not found: C/Program Files/R/R-4.0.2/Rscript.exe", when I'm actually on D disk.

I'm currently on version R 4.2.1
