Question about GnuPG Shell 1.0

[Csabi]

Hello,

I have Windows XP with GnuPG 1.4.9 installed.
I wanted to install GNUPG Shell 1.0 but when i clicked to "install" 
button, the installer told me the following:
GnuPG not installed on your system. Please, install it first.
I dont know the C programming language so i cant examine the source code 
to know how do it search the installed GnuPG on the system.
My GnuPG is installed in c:\program files\gnu\gnupg
I copyed it in to c:\program files\gnupg and tryed to install GnuPG Shell 
again, but the same error message appeared.

GPG Shell works fine but i would like to try the GnuPG Shell.

Do You have any idea to resolve the problem?

Sincerely, Csabi
