I think I may have corrected the problem with my system.
background - Windows 7 Pro, i7 (laptop), 8GB
1st - I had VS2008 and VS2010 loaded on the same machine.
Here's what i did:
1 - uninstalled VS2008
2 - reboot
3 - uninstalled Krypton 4.4.0
4 - reboot
5 - installed Krypton 4.4.0
6 - reboot
7 - now Krypton 4.4.0 is in my components tool list on VS2010
NEXT, resolving the issue with the solution file previously using version 4.3.2:
1 - start VS2010
2 - load solution
3 - go to Solution Explorer, References, ComponentFactory.Krypton.xxxxxxx (referenced control) - right click and select properties
4 - on Properties.... highlight version, go to Properties, then 'Specific Version' attribute and change it from TRUE to FALSE
(repeat for each control referenced in the solution explorer)
All the reference errors went away and it compiled correctly.
That's what it took to get me back up and running.
I hope this helps others, if they have the same problem.
