I have just had to reinstall FSX after a failed HD but now Acceleration will not install.When I click on 'setup.exe' a small box appears for a split second then nothing happens, I can find no associated entry in the application event log.AFAIK I have removed all bits of the previous install, even trawled the registry searching for, and deleting any reference to FSX.I installed FSX DeLuxe and activated it and started the default flight, then closed FSX and rebooted the PC.Anyone any suggestions of where to go from here?TIADave

Ignore this thread.I thought Accelration would install SP1, instead I installed it manually and now Acceleration is installing.
