[FATAL] [DBT-50000] Unable to check for available memory

While installing an Oracle database with Silent installation method, it threw me the below error after few seconds of running the command.

[FATAL] [DBT-50000] Unable to check for available memory.

Either it's because wrong environment variable configuration OR Unsupported OS OR lack of Administrative privileges.

For me, it was because I was running it on normal CMD, I ran it again from CMD with Administrative privileges and it worked.

PS C:\Users\parvi> dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName mydb -sid mydb -sysPassword Admin$123 -systemPassword Admin$123 -emConfiguration NONE -datafileDestination C:\app\oracle\oradata -storageType FS -characterSet AL32UTF8
