Hi All, I downloaded the ZEOSDBO-6.6.2-rc.zip file and I unzipped it. The installation under D7 was succesfull. In the old version I used the libpq73.dll, but at the moment I need the libpq81.dll and libpq.dll. I am using Delphi 7. Could you help me, where can I found the libpq*.dll files in the act...
