Cannot reinstall XE 21c

Alexis BAug 18 2025

Hi everyone,

We had an Oracle XE21c installed on a windows server 2022

We needed to deinstall and reinstall it to change the character set defined during installation and cannot be change after)

We deinstalled DB using control panel

Then we relaunched the setup.exe but it failed because services were still here

We deleted them with commande line sc delete …

Since the installer is stuck at “Destination Folder” step. The button NEXT do nothing

We tried to amend the regedit, amend the path, to rename our folder oraclexe to oraclexe_old , to remove windows Oracle account, to reboot the server… But nothing worked.

We are stuck and we dont' have more idea how to fix this, Youtube video, forums, IA, … didn't solved our issue.
If no solution we will reinstall the VM but would like to know if there exists a softer solution

Has anyone already been in the same case and can help us?

Thanks

Best regards,
