I like this change (but haven't tested it), but please ping me before merging this.

Uh, no merge conflict with #542 merged but I guess this PR still needs to be updated so that run number is written to both exe and dll?

Or is this kinda done implicitly already? ^^

Can confirm that version number is set accordingly.

$ exiftool Northstar.dll 
ExifTool Version Number         : 12.60
File Name                       : Northstar.dll
...
File Version Number             : 0.0.0.2823
Product Version Number          : 0.0.0.2823
...

$ exiftool NorthstarLauncher.exe 
ExifTool Version Number         : 12.60
File Name                       : NorthstarLauncher.exe
...
File Version Number             : 0.0.0.2823
Product Version Number          : 0.0.0.2823
...

Didn't test running game but based on the changes this should have no impact.

Code changes look fine, comment was also properly updated.
(I'm still annoyed that it's convention in C to drop the != 0 and rely on truthiness of integers but that's besides the point :P)
