Setup has detected an existing installation of NetVault Backup

Rhel 8

Trying to install netvault backup client 12.4 hybrid.

I had initially tried to install 12 hybrid, but it wasn't working. I thought maybe it wasn't compatible with rhel 8.

So, I removed it. However, when trying the new 12.4 hybrid, I receive this error.

I cannot find any left over files on the system, so there shouldn't be anything stopping this install.

I even tried re-installing 12, on the off chance I could re-run the uninstall., But that gives the same error.

So, there must be a file not named netvault, that I need to remove.

Any idea what it might be?
