We have been using PSQL ver 10.3 Workgroup Engine for a long time on XP. We just upgraded our production developement machine to Win 7. Each time we launch PV we get an error 161. We have to uninstall and re-install PSQL ver 10.3 again. Then when we reboot, again the 161 error and we again have to uninstall/re-install PV ver 10.3. Any suggestions?
