RAV852 setup ignoring %programfiles% on XP

I've also sent this to support. Anyone else seen this behavious

I've just re-isntall rav852 on windows XP, and the setup has ignored the value of
%programfiles% which on my system translates to c:\apps and it has created a directory
"c:\program files"

it has installed "Setup Log.txt" in "C:\apps\Replay AV 8", so it must have parsed %programfiles% at some point.

Can you issue a fix?

i think the offending line is
Default value = C:\Program Files\Replay AV 8


No other application I've installed has walked over my filesystem like this
