The question is How to Enable or Re-Install Expressgate when it is reports the ' Incomplete Installation ' error. It does not need to be disabled if it doesn't work.
Reading the manual is excellent advice. Please do so before rendering your expert opinion. The manual does not address the configuration issue or the loading of an updated ExpressGate.
Searching AsusTeK forums and Googling elsewhere shows many others are similarly at a loss. Expressgate apparently does not work with RAID, however it also doesn't work with IDE. So something else is involved. Getting updated Expressgate software via AsusTeK does not seem to work.
Constructive remedies or further problem definition would be nice.
