Oracle 12c Installation in Windows 7 error INS-30131

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:

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

I finally got the answer for this error, this was because of the machine name being big. While setting up a new machine we should ensure that the machine name is not bigger then the bios name. which is 15 chars. This will definitely work.

I had the similar issue and failed even after trying many solutions.

Finally, I end up doing the following which might help some one but strongly advise you not to do this production environments.

Following Workaround is available to install database/client software if administrative shares is not enabled :

 For client installs, run the installer with following arguments:

setup.exe -ignorePrereq -J"-Doracle.install.client.validate.clientSupportedOSCheck=false"

 For server installs, run the installer with following arguments:

setup.exe -ignorePrereq -J"-Doracle.install.db.validate.supportedOSCheck=false"
