I just purchased the City Bus Simulator :
City Bus Simulator 2010 - Regiobus Usedom.
I downloaded the zip file and started installation process by running the setup file as administrator (as you adviced in this forum).
After getting to the stage of installation path selection, I get the following error message :
"The City Bus Simulator could not locate on your system.
Please check the City Bus Simulator path your self. "
No alternative path i gave (tried to change the 'Program files' path) had worked, and i always get this message, and installation won't progress.
I'm working with Windows 7.
