How can I uninstall/clean a previous Jamf Pro installation on a Windows Server?
I want to install a fresh new Jamf Pro 10.21 on a Windows server. Previous version is/was 10.19. I don't need the old data anymore, as this will be just a test server.
- I dropped the MySQL DB and created an empty new schema.
- I removed the JSS program folder.
- I removed all JSS environment variables.
- I restarted the Windows server.

But if I run the Jamf Pro 10.21 Windows installer it always tries to upgrade my server, which of course fails. It somehow still detects a previous version and will not allow me to install a new one.

Which folder/files do I need to remove, so the installer don't switches in the upgrade mode?

OK, now the installer runs in new installation mode. I deleted MANY "Jamf" and "JSS" entries manually from Registry and restartet the server again.
(Btw, I forgot to run the uninstall Jamf Pro in control panel. Shame on me. So maybe I had no issues, when running the official uninstaller first. ;-) )

I'll admit, this is not my area of expertise... specifically. However, is there a reason why you wouldn't just start from scratch? Wipe the thing and rebuild it as you want?
