OMCI 8 VBS Sample Scripts Error\don't work

Hi,

None of the OMCI sample scripts seem to work.  Consistently I get Invalid parameter - swbemobjectex error for the line:

Set returnValue = objInstance.ExecMethod_("SetBIOSAttributes", oInParams)

WMI is know to be working on the machine as other WMI scripts work.

I tried uninstalling\reinstalling OMCI 8 on several machines.

I tried install OMCI 7.6 and 8 togher.

I tried removing the authorization part of the script as I have no BIOS passwords.

I see other people have posted this issue on the forums with no resolution.  Can someone assist ? 

Which class has "Chassis Intrustion Status" reported ?  It's not in the documentation , only for OMCI legacy versions.

Here is the script that generates the invalid parameter error.
