Re: Error SQL_NO_DATA after installation HOPEX V2R1 and regedit error
Regarding the registration errors, there definitely seems to have been an issue in the registry either uninstalling the old version or installing the new. have you tried uninstalling, rebooting the server, then reinstalling using the "...\HOPEX_V2R1_U02_785-4903\Mega\DISK1\Setup.exe" in "Run as Administrator" mode?
as for the data access issues, it seems you only performed part of the manditory data upgrade steps outlined in our "how to Migrate to Hopex V2R1" online document. If you have access to the document, I would recommend leveraging it to finish the upgrade.
