The problem shows up when a different than default directory is selected 
during gpg4win 1.1.3 install. It manifests itself when gpa.exe is 
started and fails to find the engine. It is caused by mismatch between 
gpg4win using newer approach of registering "Install Directory" and 
"gpgProgram" strings in "HKLM\Software\GNU\GnuPG\" key and GPGME relying 
on either "HKCU\Software\GNU\GnuPG\gpgProgram" (note the HKCU vs HKLM) 
or on the program being in the default location. There's a note in the 
"src/inst-gnupg.nsi" that relying on "gpgProgram" key is an old style 
and sure enough the newer version of GPGME (although also 1.1.6) does 
uses the "Install Directory" to find all the necessary gpg.exe, 
gpgsm.exe, and gpgconf.exe.

On related note, the new GPGME still checks for gpgProgram in HKCU and 
not HKLM rooted location. On my machine I noticed that there was entry 
in there which looks like left-over from some previous installation and 
(as expected) it is not removed by the newer version of gpg4win on 
install/uninstall. This caused even newer GPGME to assume a wrong 
location for gpg.exe. I removed that registry value on my machine but I 
suspect other users may run into similar problem.

Hope it help.
