Hi,
I downloaded these samples (subject line) and when I double-click (or
right-click & choose "open with") on the .sln file, VS2005 won't launch.  
When I hover the mouse over the .sln file in IE, the pop-up window indicates
"unrecognized version".

I found this suggestion,
http://msdn.microsoft.com/newsgroups/managed/default.aspx?dg=microsoft.public.vc
.ide_general&mid=cc3123d0-493d-412f-b5dc-1ae7aaa4b73c&sloc=en-us,
which worked but the .sln file remained unaltered -  I still could not open
open it by double-clicking or "right-click->open with".

Short of creating a new project and porting the existing files into it, is
there any way to correct this issue?

Thanks.
