I installed it (and update), and the SDK. But when i try to start it with the desktop shortcut i get a message about a mission gameinfo.txt. When i try to start it via steam i can see the start screen for a few seconds and it says "hl2.exe" has stopped working and something about a "libcef.dll"
So, i tried it again. I downloaded and installed "Boogaloo Kappa Plus 7/24 Windows" and "Source SDK Base 2013 Multiplayer" then, restarted steam and started the game from Steam Library. But 2 Seconds after the title screen shows up, the game crashes. (hl2.exe has stopped working). I did not install the update this time.
As weird as it may sound, but deleting the file "libcef.dll" from "\Steam\SteamApps\common\Source SDK Base 2013 Multiplayer\bin\" seem to have fixed the problem. I could start the game, and play.
Yeah im glad too. I used google to try to find a solution, and in an very old post on the steam forums i´ve found a user with the same problem, (but with another source game). He deleted that file out of rage, and his game worked, lol.
Anyway, Double Action Boogaloo is an awesome game, it reminds me of the good times i had with Action HL and The Opera back then. I wish you good luck with green light. Already voted for you.
