Boot-Time scan grayed out? 60 day trial limitation?

trying out Home Pro and the Boot-Time scan in the Scheduler is grayed out. Is this a 60 day trial limitation? Vista x64? Me not reading the manual?

Thanks,
Monte

did a search :o looks like it’s a x64 issue. coming in a later version.

:-*

Yes it is not available currently in 64bit OS and not a 60 day trial limitation. Hopefully this will be in a later version of the new avast 5, provisionally for version 5.1
