I saw your pc requirements on the product Page of ZürichX.
The FS9 version is compatible with FS9 with the 9.1 upgrade installed, and runs under Windows XP or Vista 32 bit edition.
The FSX version is compatible with FSX+SP2 minimum, or FSX+Acceleration Pack, under Windows XP or Vista 32 and 64 bit editions
So, i have Vista Home Premium 64-bit.
I have fs9 and fsx.
Can i install Zürich X under Vista 64-bit with any trich?
Kind Regards from Switzerland
