Upgraded my installation project (basic MSI) from 10.5 to 11. Re-built with the standalone builder, ran the install. Right off the bat recieved an error message about how I didn't have permission to write to "\HKEY_LOCAL_MACHINE".

After I installed none of my shortcuts had icons. (checked with orca, Icon table has only 1 entry: ARPRODUCTICON.exe)

Checked further, some of the feature conditions had been ignored while installing.

Reverted to 10.5 for now until I figure out what's going on, just wanted to give a heads up to anyone else who might run into problems.
