I get an error report when I put "-dev" after "ProcName=dow2.exe" in the rev thing. So it looks like this "ProcName=dow2.exe -Dev" Help?
[Loader]
# Specify the name of the application to load.
# You can also specify the command line.
#
ProcName=dow2.exe -dev
# Specify the location of the original steamclient.dll
# which comes with Steam client
# You can comment this line out if the game doesn't use it
#
SteamClientDll=C:\Program Files (x86)\Steam\steamclient.dll
That is how mine looks
