When I try to load Oracle 11gR2 64Bit on my PC with Windows 7 Enterprise 64Bit, it does a system check to make sure my PC is "acceptable". All tests fail with an error message like Physical Memory - PRVF-7531 : Physical memory check cannot be performed on node "PaulK_PC" PaulK_PC is my PC. The recommended action is Ensure ability to access the node specified and view memory information. According to the Account Manager, my account is an administrator. I also right-clicked the Oracle setup.exe file and selected "run as administrator". Same result. I have enough ram and enough disk space for installation. I downloaded Oracle from their website for a database class, so I have no customer support options. Any help is appreciated. Thanks
