Whilst preparing the demos for my [TFS 2012 ALM session on Wednesday (still places available of you are in the Yorkshire area)](http://www.blackmarble.co.uk/events.aspx?event=How to Plan your Application Lifecycle Implementation with TFS11), I got the following error whey trying to add a new solution of sample code to TFS

Access to the path ‘C:ProgramDataMicrosoft Team Foundation Local Workspaces43519e4-72cf-4cd0-a711-f4bb8b817f30TYPHOON;432cfb95-26d6-4a68-af26-b102c950a90dproperties.tf1’ is denied.

It seems that the ..4535… folder had been created when I was running VS2012 using ‘run as administrator’. When I tried to browse it I was prompted for UAC elevated privileges. So if I was not running VS2012 as administrator I could not access the folder. For me the solution was to just delete the folder and let VS/TFS recreate it. I had no checked out files so it did not matter.  Once done all was OK

One to key an eye on
