It's possible.
You have to firstly make sure hidden files are shown, then go:
C:\ProgramData\Xfire
Then open xfire_games.ini
Next step is to find Race07. Which should looks like this:
[5233]
LongName=RACE 07
ShortName=race07
LauncherDirKey=HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam\InstallPath
LauncherExe=steam.exe
DetectExe=SteamApps\*\race 07\Race_Steam.exe
InstallHint=steamapps\*\race 07\mss32.dll
Launch=%UA_LAUNCHER_EXE_PATH% -applaunch 8600
_LAUNCHER_EXTRA_ARGS%
_LAUNCHER_NETWORK_ARGS%
RunElevated=1
And make the race07 section look like this instead:
[5233]
LongName=RACE 07
ShortName=race07
LauncherDirKey=HKEY_LOCAL_MACHINE\SOFTWARE\Valve\Steam\InstallPath
LauncherExe=steam.exe
DetectExe=SteamApps\*\race 07\Race_Steam.exe
InstallHint=steamapps\*\race 07\mss32.dll
Launch=
_LAUNCHER_EXE_PATH% -applaunch 8600
_LAUNCHER_EXTRA_ARGS%
_LAUNCHER_NETWORK_ARGS%
RunElevated=1
InGameRenderer=D3D9
InGameFlags=USE_PRESENT|ENABLE_MOUSE|USE_DINPUT_MOUSE
This works, however, at every xfire program/game update this fix will have to be re-done.
