I uninstalled .Net Framework 3.5
Since the uninstall did not require me to restart windows (I know I have to restart in order to reload .Net Framework 3.0 correctly

), I went ahead and opened Hoster 4.05 just to see what would happen. Sure enough right as the logo video was finishing the program crashed.
Hoster 4.05 does not like .Net Framework 3.5.
I restarted my computer and Hoster 4.05 ran like the program it is, solid as a rock.
Conclusion: Do not upgrade to .Net Framework 3.5.
Thanks again for your help finding this James.
