I’ve downloaded the osFirmwareUpdater and unzipped it. I’m running Windows 7.
When I run the windows version I first get the dialog box to authorize the application to run, and then I get another dialog which reads “Windows cannot find ‘javaw.exe’. Make sure you typed the name correctly, then try again.”
After pressing OK, another dialog appears which reads “Error calling ShellExecuteEx()” (Dialog box title is Processing Error). I press OK and the install terminates.
