I was getting the following when I tried to install:
02/18/14 11:51:17: rinstInstall begin
02/18/14 11:51:17: Init 50 60 C:\Windows\TEMP\asw4BA4.tmp C:\Program Files\AVAST Software\Enterprise Administration\InstPkgs NULL 0
02/18/14 11:51:17: Store
02/18/14 11:51:17: Domains: hdisd,
02/18/14 11:51:17: Init HDISD\RTG-005
02/18/14 11:51:17: RTG-005: install already in progress
02/18/14 11:51:17: RTG-005: Finished with error
I had already installed successfully on a few test workstations. Then still testing accidentally started to deploy to all the network PC's. I then canceled the install and could not install again. After trying several things I restarted the admin console service and it seemed to fix my problem. If you need more info on what I did let me know here.
