In the VBoxGuestAdditions.iso file in 4.0.0 version, I was following user manual and try to execute VBoxLinuxAdditions-amd64.run on a 64 bit host. Runnung Ubuntu 10.10 64 bit as guest. However I don't see VBoxLinuxAdditions-amd64.run. I see only 32 bit version and running it gives checksum error.

Am I missing anything?

User Manual Bullet 3 http://www.virtualbox.org/manual/ch04.html#id489939

It's in the changelog:

Linux Additions: combined 32-bit and 64-bit additions into one file

They missed it in the manual to fix. Reminds me to fix it in my howto too.
