Run AutoUpgrade.exe 

This is dirty hack to update agents on all nodes.

It uploads task which kills agent and starts new version installer:


hxgrid_agent_setup.exe /VERYSILENT  /SUPPRESSMSGBOXES


This app should use hxgriduser.dll of prev version and installer of the next version.

Unfortunatelly, app can not upgrade suspended agents. 
Should implement some "DISABLE_SUSPEND" network command for agents.
