incompatible with cfosspeed | 3.9.95478.509 x64

OS: Windows 7 x64 RC1
CIS: 3.9.95478.509
incompatible software: cfosspeed 4.52 x64 (

steps to reproduce:
install CIS, reboot, install cfosspeed, installation fails
install cfosspeed, reboot, install cis, reboot, cis won´t load firewall

tried numerous times in different order, with and without reboots, in safe mode, either cfosspeed won´t install its driver or cis won´t load its firewall and complain about problems. cis diagnostics finds problems but can not fix them.
both softwares used to work together in Vista x64 and Win7 x64 Beta, though I used CIS 3.8.something in Win7 Beta but I do not have the installfile so I can not test if thats the issue.
cis diagnostic is attached!
