Just to follow up a bit, I've pared everything down to the failing call. My
test.pl contains:
use Win32::OLE;
$wmi = Win32::OLE->GetObject('WinMgmts:');
print Win32::OLE->LastError();
and it outputs:
Win32::OLE(0.1707) error 0x800401e4: "Invalid syntax"
after character 0 in "WinMgmts:"
whereas on a WinXP Pro system, the same script simply outputs
0
Any thoughts?
