Hi Rick,
Please go to the registry to check and see the key MSOLEDBSQL exists under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Sybase\PowerBuilder\19.0\Vendors\.
If not, please try to use regsvr32 to re-register pbmsoledbsql.dll to add this registry key, you can execute the following command:
regsvr32 "C:\Program Files (x86)\Appeon\Common\PowerBuilder\Runtime 19.2.0.2670\pbmsoledbsql.dll"
This issue might be related to permission. To further locate the root cause of it, it is suggested you upload the PB installation log files for us to analyze. The default path is C:\Windows\SysWOW64\AppeonInstallLog.
Regards,
Ken
