Hi ALL,
12c
Win7 64bit
I am installing 12c, but I encountered error:

[INS-30131] Initial setup required for the execution of installer validations failed.
Cause - Failed to access the temporary location.
Action - Ensure that the current user has required permissions to access the temporary location.
Additional Information:
Exception details - PRVG-11322 : One or more node names "oracle_training" contain one or more of the following invalid characters "_"
What temp file should I grant permissions to?
Thanks a lot,
jc
