Android Tutorial .net error when starting b4a

When I try to start B4A, I get a .net error that says

"Unable to find a version of the runtime to run this application"

I tried uninstalling and reinstalling .net, but that didn't help.

Suggestions please?

Windows XP users should install .Net Framework 2.0 if it is not already installed.
