Help！I can't update my GSA-4160B!

#1

When I run the Firmware Update software (for example: GSA-4160B Version A303 Firmware Update),it always says “An invalid argument was encountered.”

My OS is Win2003 enterprise. Please help me! Thanks!

#2

Only idea I have: Do it in safe mode (2k3 has sth like that, hasnt it?) and as administrator.
