I'm trying to install System Manager 2.2 on a Windows 7 64 bit machine with only Java 32 bit installed and get a message "OnCommand System Manager requires a 64-bit Java 7 software. No 64-bit Java software detected". The requirements only state that 32 bit Java is required. Why do I get this message?
Actually, the System Manager download page states the following:
"Installing 32-bit or 64-bit JRE depends on the operating system. If you have a 32-bit Windows operating system, 32-bit JRE must be installed. Similarly, if you have a 64-bit Windows operating system, 64-bit JRE must be installed."
Since you are running a 64-bit OS, you should install a 64-bit JRE.
I was having a similar problem. In my case I upgraded from Java 6 to Java 7 but the System Manager installer was still seeing Java 6 and throwing and error. I followed Chris Maki's advice and tried the manual Java 7 installer, it worked fine and I was able to install System Manager.
