I just tried the psqlodbc-08_02_0200 msi on Windows XP Pro SP2. After setting up an odbc link (identical to a 08_01_0200 working one), and clicking "test", I get odbcad32.exe: Error signature: AppName: odbcad32.exe AppVer: 3.525.1117.0 ModName: psqlodbc30a.dll ModVer: 8.2.2.0 Offset: 00015a22 Nothing hits the postgresql server - all dead beforehand.. Thoughts? Debugging psqlodbc.msi ? Cheers, Patrick
