I am using Katmai Feb 2008 CTP on 64 bit enterprise vista.I am getting following error, when I am trying to adddafult detail attributes with a role in report model. getting the same error when trying to addfilter in a report model.Access to th path 'C:\Windows\system32\config' is denied. ..Aqurs

..Hey no one have any clue..?????????????????? .. Aqurs

I believe you can avoid this in Vista by running Visual Studio as Administrator.

I am getting this same message. I am running Vista and running Visual studio as Administrator. My user account is also in the administrator group. I am getting this when trying to edit an attribute of a reporting model in BIDS for SQL Server 2005. Any other ideas would be appreciated.

I received the same error. I just closed the solution and re-opened - but not from File -> Recent Projects. Try navigating to the solution through windows explorer and launch the app directly from the sln file. The error disappeared for me.

The error disaapears , but now I cannot deploy...says access denied...?? Have to get out and restart as "priveledged" user, for deploy to work...

That worked for me too. Thanks

Lauching the 'Report Model.sln' directly works. The error disappears and when you right-click in the'Detail View' and create a 'New -->Expression' you get to the 'Define Formula' dialog boxrather than get the error message 'Access ... is denied'

Good Job Eric! I tried your solution and it worked! Thanks!

Surprisingly enough, running my sln from Windows Explorer instead of the recent list worked for me too! I was able to access the Expression popup and deploy just fine. Nice work, bpeter and Eric Lindberg---thanks for taking the time to post.

Yep, I had the same problem and I closed Visual Studio and started up the sln from windows explorer. Bizarro is all I can say. Thanks for the tip on what to do.KathyL

The answers here are all work arounds, much appreciated as they are, but what is the cause of the problem and what permissions should be granted? Actually found it here; https://connect.microsoft.com/SQLServer/feedback/details/334796/model-designer-fails-on-acces-to-c-windows-system32-config?wa=wsignin1.0 Set the startup folder for BIDS in Start menu to "%ProgramFiles%\Microsoft Visual Studio 8\Common7\IDE\". Right click on the Visual Studio shortcut in your start menu, select "Properties," then set the Start in property. On 64-bit Windows 7, "Program Files" is "Program Files (x86)"
