Windows XP 64 bit

[Shadowcaster]

Hi Chaps

Not been here five mins and already asking questions. I bought some more memory for my computer so I now have 4 gig, in order to access this I have upgraded to XP 64 bit. Now everything was going really until it came to load VFR Photographic Scenery Generation X from Horizon Simulation, I click on the setup icon and it asks if I want to install in FSX or FS 2004, I select FSX and then nothing. No drive activity just as dead as a dead thingy, I know that the Disks are OK because it worked with no problem on XP 32 bit.

I have looked on the website and the documentation and nowhere does it say that it is not compatable with 64 bit XP.
Am I being thick and missed something or is this a known issue

Cheers
Rich
