What is wrong with my inf? a bit off topic
I want to have the app installed in a sub folder off of a folder in Program Files but I can not get it to work. Where am I wrong?

What I want: \Program Files\PLUSPC\PocketMAP\pocketmap.exe

I have tried:

[Version]
Signature="$Windows NT$"
Provider="PLUSPC"
CESignature="$Windows CE$"

[CEStrings]
AppName="PocketMAP"
InstallDir = %CE1%\PLUSPC\%AppName%

and many variations thereof, but if I deviate from InstallDir = %CE1%\%AppName% it ignores the extra text and installs in InstallDir = %CE1%\%AppName% anyways. I am confused and frustrated. Any help is appreciated
