First of all, sorry if it's already asked before, but I have not found it on the forum. And sorry if this is not in the correct place of the forum

Installed RBR. Patched it to 1.02. Ran it. It worked. Sweet.

Installed RSRBR 2015, car packs, and track packs in that order. Everything seemed to have installed smoothly. Started RSRBR 2015 up just fine. But after choosing car/stage, etc. and pressing GO(or any of the other launch options) nothing happens. The mouse icon changes like its thinking about something for a moment but nothing actually happens.

And now the same thing happens when I try to run plain old stock RBR (after having installed RSRBR 2013)...

I've fresh installed everything 3 times now and this still happens.

Absolutely no idea what is going on... Anyone have any ideas that would help me get this ridiculously awesome mod working?

To be clear, absolutely stock RBR on its own works fine.

2015 I presume

Have you made data execution prevention? (See installation tutorial)

TROUBLESHOOTING UTILITY  (Utilitaire de dépannage)
Download and launch this utility of repair
Depannage RSRBR2015

Once launched the utility click button  "Complete analysis"
When the analysis is completed, DO NOTHING, close the software, come directly to the forum, and "Paste" in the field without removing the text that appears.

Hola, ¿que sistema operativo usas? ese problema que comentas le suele a pasar la gente con windows 7 y suele deberse a un problema con la carpeta en la que se instala el juego, hay un tutorial de instalacion (como dice obelix en su comentario) en el que vienen los problemas mas frecuentes. Si instalas el juego dentro de la carpeta archicos de programa suele dar ese error, tienes que instalarlo en la carpeta raiz del disco duro.

Cuando instalas el juego supongo que lo haras en como administrador ¿no?

P.D. For the admins, I´m sorry for answered in spanish  

Tengo windows 7 y lo tengo instalado fuera de archivos de programa. He seguido el tutorial en español. Por la tarde voy a probar lo que me ha dicho el compañero de arriba a ver que tal. Gracias a ambos  

I have windows 7 and I did not install the game in program files. I followed the Spanish tutorial. At afternoon I will do what Obelix suggested and see what happens. Thanks very much both  

If you do not give the report from the Troubleshooter I can not guess what your operating system.
Where is the analysis requested? Without it I can not help you.

I'm idiot. I did not do the data execution prevention. I apologize for the inconvenience. Thanks very much again.
