looking thru my machine.config i found previous references to mysql and deleted them.  The msi was then able to install the web providers.

Visual studio was still not connecting so i then uninstalled everything and ran the msi installer again.  now it works.  grrrr..

Tim, it might be useful to use default uninstall procedure provided by windows to be sure you removed everything from the last install...

Other than that, I'm doing this on weekly basis (uninstall/install 5.x, 6.x) on W2K8SEx64 box with both VS2005Pro and VS2008Pro and haven't had any troubles in months.

the same with 6.3.0 (alpha?)
After i changed from 2010 RC1 to 2010 Ultimate the providers in studio stopped working. Applications still work.
i could not uninstall the connector,
"Mysql connector NET 6.3.0 setup ended prematurely because of an error...".
Then: i removed it from installed programs list with msicuu2.exe.
Removed all references from machine.config.
Tried to install 6.3.0, 6.3.1 - the same.

Installed 6.2.2 - success
uninstalled it. 
Still 6.3.0 and 6.3.1 did not install.
installed 6.2.3...

mysql data connections in 2010 still does not work. gonna reinstall windows...
