Oracle 12c Installation in Windows 7 error INS-30131 I am trying to install Oracle 12c in a Windows 7 x64 computer and after a while I get this error:

SEVERE: [FATAL] [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.

Summary of the failed nodes

- Version of exectask could not be retrieved from node "XXXXXX"
- Cause: Cause Of Problem Not Available
- Action: User Action Not Available


Does anybody have an idea how to solve this problem?
I found the problem. For reasons I don't understand Oracle needs access to the file system through the administrative network share (i.e. \computer\c$) and I had disabled it.

Things to check to solve this issue:


Remove your computer from workgroups.
Set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System DWORD value LocalAccountTokenFilterPolicy to 1
Set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters DWORD value AutoShareWks to 1
