Hi, Werner.

When I have to make use of "idea.dll" so that I can decrypt messages that 
were encrypted with it, I then use Gpg 1.4.x, and I have it in an altogether 
separate folder from the real installation of Gpg 2.0.x. I could not agree 
with you more in regard to its comparatively inferior algorithms, but that 
does not preclude my needing it from time to time.

Is there any reason I should not place it in the same folder as the gpg.exe 
version 1.4.x and then make reference to it there? Thanks.
