Oracle 12c client installer error I'm trying to install Oracle client 12.1.0.2.0 (32-bit) on a completely clean copy of windows Server 2012, and I'm hitting a problem.

The installer runs fine until it gets to the final part - the net configuration assistant. An error message appears and says "[INS-20802] Oracle Net Configuration Assistant failed.". Here's the relevant part of the log file that is generated (I can post the entire thing if requested, but here's the bit with the actual error occurs):

Here are a few things I have tried:


turning the firewall off
disconnecting from network (clutching at straws!)
running the installer as administrator
re-downloading the client installer from Oracle, in case it had somehow been corrupted


None of these things made any difference. I have successfully installed this exact version of the client on a Windows Server 2012 PC in the past and it worked fine...

Has anyone else encountered this issue?
The install/oraparam.ini contains the following lines (even in a fresh download):

#MSVCREDIST_LOC flag will provide the name of the exe that is being shipped in stage/ext/bin  
MSVCREDIST_LOC=vcredist_x64.exe


This is incorrect because you need the 32-bit version (x86).

Now if you check stage/ext/bin, there is a file vcredist_x86.exe, and obviously no x64, since it is a 32-bit installer. Try editing oraparam.init and fixing the above line to:

MSVCREDIST_LOC=vcredist_x86.exe


Another possibility is that you need to install the Microsoft C++ 2010 Redistributable manually: http://www.microsoft.com/en-us/download/confirmation.aspx?id=5555
