Can't run Update Manager

Hi Everyone,

We're running Op Manager 8051 on Windows 2008 / 64 bit. I notice I can't run the Update Manager to install the latest hotfix. Here's an an output of the error when I try:

C:Program Files (x86)ManageEngineOpManagerin>UpdateManager.bat

I also noticed I can't backup the database either. It says it fails to start MySQL. I've tried running both updatemanager and the backup command with the choice "run as administrator" as well, even though I already have admin right myself. No luck. We downloaded the 64 bit installer but I notice that the some of the processes (mysql, java) are still 32 bit.

Any thoughts?
