- Enable administrative share for C$ (Please check with your System Admin to do this or See Microsoft document http://support.microsoft.com/kb/314984)
- Check that it is ok:
- net use \\c$ should work
- the current user (i.e. user in administrator group) should have all privileges on the default share
- Retry the installation
- Remove the administrative share again

- Stop OracleRemExecServiceV2
- ( This service is having a intelligence .Once someone tries to stop it this service gets deleted. This is due to the fact ,that this service is not running from the Oracle Home like other oracle services ,but from temp . For example : C:\Users\AppData\Local\Temp\oraremservi... )
- Then try to install the Oracle 12c 32-bit or 64-bit on the same Microsoft Windows x64 (64-bit)
