I recently installed Oracle 18c Express Edition on my Windows 10x laptop.
When I tried to run DBCA I got this message:

When I researched this error one suggestion was to use a TRY/Catch block to trap this error; I shouldn't be trying to change DBCA.
My background is with Oracle 11g on Windows servers; I am researching a project to migrate databases to Oracle 19.
I would have preferred to install an Oracle 19 Express edition but apparently that does not exist.
My account with oracle is a "free" one so I don't have access to knowledge base articles.
I am curious - did something change between Oracle 11 and Oracle 18/19 with respect to language support.
Amy assistance would be appreciated.
