W10 Crystal 8 Oracle 01019 error

What do we need to change to get Crystal 8 to work on W10 when Toad is also working on it.

We installed Crystal 8 and it was working with our oracle database. But then we installed Toad 4.3 and Oracle 11g instance on the workstation. Toad works fine BUT Crystal 8 now gets the ORACLE 01019 error. See attached image of the error. I was researching and found this about a similar case but it was for a W7 machine. It had instructions for altering the register for an Oracle setting. But that same kind of setting is not in my W10. This is the link to that instruction:

So, I am thinking perhaps there is a similar but different adjustment needed in W10 register. Can anyone help with that? oracle-01019-error.pngregestry-editor.png
