Thanks for that. Though I am just starting to have time to work on the Images for next school year this is still an issue with only a couple devices. This school year we ran a pilot with Dell Venue 11 Pro 5130s (for Students) and 7130s (staff). Using SCCM to deploy our images, Avast had no problem installing as an SCCM application on the 5130s that are 32bit. The staff 7130s, 64bit, have a task sequence error when they get to Avast and i have to install it manually. At first I thought it was a 64bit issue, but our lab desktops (Dell 380's, 390s Windows 7 64bit) had no problem installing avast in the task sequence. I will give this a go with those Tasks that just wont work. If only Avast would give us an MSI option things would be much easier.
