Wilco 777 Help

I bought Wilco's 777 for FSX, and every time i try and install it, i gt to the screen where it says creating directory, and every time it gets to the point where it tells you to press next, it keeps coming up saying "please select you correct FS2004 directory"



And when I went to Wilco's web site to fill out the form, first they got mad i did not fill out the help form that I could not find at first so they sent me the link to that, and they wanted to know every thing about my PC including what I used to extract the file and my sound card, but after finding all the stuff that had nothing to do with my question this is what they finally had to say:
So right now I'm at the point that if I can't get this installed, I will send it directly to them with a nasty letter thanking them for nothing
, or just giving it away to what every SimV member wants it.

Dear Customer,
Below are important notes about our products and the Operating Systems :
* Although they may work with our products, we do not technically support the use of 64 bits Operating Systems. We only technically support 32bits Operating System (Windows XP or Vista 64 bits excluded).
* In order to avoid Crash To Desktop (CTD) when using Flight Simulator X versions of Wilco products under Windows Vista, they must be installed under full administrator rights. Then, be sure to give full rights to your complete Flight Simulator folder.
Consult your Windows Vista documentation or your system administrator to find out how to configure these settings or look at our SUPPORT page.
* Under Vista, make sure to run the installation with full Administrator rights.
* We do not support the use of our FS2004 add-ons under Windows Vista (although they may work).
Best regards,
Wilco Publishing
