Hi,I have just purchased PMDG 747-400 on disk and I am having trouble installing it.I get to the stage where I get a message: 'Installation cannot continue. You do not have Flight Simulation installed'. Pressing OK has no effect, I just cannot get any further with the installer.I have FS 2004 installed on my D: drive and yes I have deleted it and re-installed it in the past.I cannot navigate the installer to the D: drive and I am not sure how to update the registry.Any help would be appreciated.Thank you,bhp.

Here's a freeware tool that will fix your registryhttp://www.flight1.com/view.asp?page=libraryHope that helps :)

Hi Jeff,Brilliant, installation completed.Many thanks,bhp
