2) Run the localizer tool in the VM to get the old locale name in place.
3) Run the installer.
I just tested that and failed at the same step.
My understanding is
- The installer has localization options to choose from or default localization (which is Turkish_Türkiye.1254 in new VMs, it was Turkish_Turkey.1254 in the past).
- I cannot make the installer select something else other than Turkish_Türkiye.1254 it is hardcoded in it. So Turkish_Turkey.1254 cannot be selected in the installer even if it is installed in the OS.
- Even if I can add a new locale to the OS, I cannot make it the default.
