Checking whether my pgAdmin III is a 32 or 64 bits version I need to check if my pgAdmin III is a 32 or 64 bits version. Where can I find this information? The About... menu in pgAdmin GUI does not mention it (only the version number like 1.20).

I've looked for this on the net, without success...

EDIT:

I get a win32 error when pgAdmin crashes (connection lost). See image below (sorry my Windows is a french version):
Your image path may give that away:

get-wmiobject win32_process | where {$_.Name -like "pgadmin3.exe"} | select -property Name,ExecutablePath | fl
