Na its not RTM
Escrow is the engineer or dipstick,numb nuts idiot who signed off on crap because believe it or not MS does employ engineers who know less then you or me about this stuff.
I give you a fine example
remember XP sp3 and the LLTD fiasco?
I came up with a fix 6 months before Microsoft released a fix, its on my blog.
http://x3webworx.wordpress.com/?s=lltd
its the bottom article and the top is MS lovely fix which to get you had to sign in to accept a disclaimer get your OS WGA scanned then you were redirected to a page with the download.
After that I swore never to fix any MS crap.
Anywho this bug cant be reproduced...
your custom install paths are wrong, Em pretty sure the data and program install paths cant be same unless your using a flashfxp.portable file. Essentially an empty file with no extension with that name
