PFE 2.1 address the problem of running PFE on a Vista 64 system.
For Vista 64 users only.
You have two options.
#1 - If you purchased/downloaded PFE V2.0 and have a slow internet connection and really would prefer not to download the complete installer again please download the following installer patch...
http://www.ocs-support.co.uk/pfe_update ... stem64.zip
Unzip it to a temporary folder on your PFE system then run it. You must choose the CORRECT installation path to PFE when requested... for a default installation this will be C:\Program Files (x86)\Aerosoft\PFE
Once complete PFE should run fine on Vista 64
#2 - If you don't mind downloading the complete installation pack again please revisit your Aerosoft account and download the latest full PFE V2+ package, which includes the above Vista 64 fix.
Please make sure you run the file with administration rights by right clicking on the file and selecting "run as administrator"
