png.exe filewill not allow mod tools to download.

Alright, so...I'm not that new to modding, though this would mark my first attempt at modding something for Don't Starve. Up until this point, everything went smoothly. My Steam account will only send the modding tools to the "downloading" folder, and won't send the actual files to the folder it should be in under "common". This is the error I received, and though I'd tried my best to figure out the issue myself (and not kick-start my account here with a dopey question), I haven't succeeded.

Any attempts to manually move the png.exe file were overridden by the computer itself. It states I don't have permission to move it, and even after editing security setting in properties, it did nothing. If anyone has any idea what's going on, help would be very much appreciated.
