I can try :)
Basically I needed to install a more recent kernel.
How you install this depends on what Linux distribution/type you are using.
You need to install the kernel itself and the kernel headers.
In Debian these are named (for example) linux-image-3.2.23 and linux-headers-3.2.23
You could try this command:
sudo aptitude search linux-image
Look at the output, then install the appropriate kernel, e.g. :
sudo aptitude install linux-image-3.2.28-3 linux-headers-3.2.28-3
Those numbers above are just made-up examples :)
Then after that is installed, restart the computer so you are using the new kernel, then try again to install the ActivInspire software. Hopefully the errors messages are gone, and it all works.
Good luck!
