I just created my first ASP.NET Version 4 app using Visual Studio 2010 and SQL Express 2008.
I copied the files to IIS and run the default.asp. This loads the programs main menu. So far so good.
When I open the read webform and do a read of my database I get the following Error:
Server Error in '/Diary' Application.
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.
Any idea how to fix this error?
Did you look at support articile for the very issue.

I opened my web project today and for some reason I could not gain access to my database files. I get the following exception whenever I try to add, edit or refresh my database:
A network related instance specific error occurred while establishing
a connection to SQL Server. The Server was not found or is was not
accessible. Verify that the instance name is correct and that SQL
Server is configured to allow remote connections.
I took a look at my connection string for any spelling errors and deleted my database and replaced it in the folder I had it in. I can't seem to find a fix for this so any help would be a appreciated. I am using Visual studio 2008 for this web project.
This sounds like the same problem that I had myself awhile back. My problem was that my SQL service pack 1 did not install properly so I had to install Microsoft SQL Server System CLR Types, Microsoft SQL Server 2008 Management Objects and Microsoft SQL Server 2008 Native Client. After that I could create new SQLdatasources but I could not edit the ones I had previously before my problem. I had to restart my computer in safe mode and delete my SQLEXPRESS folder then recreate the database connection in visual studios. When I finished that everything worked fine.

my asp.net application runs successfully in development server of visual studio. but when i deploy my application in IIS it generates the error as follows
Failed to generate a user instance of SQL Server due to failure in
retrieving the user's local application data path. Please make sure
the user has a local user profile on the computer. The connection will
be closed.
what are the necessary changes that i should do in my application. also guide me how to deploy my database on IIS.
What is your connection string?
More specifically, I am wondering if you are using a .mdf file as your database.
If this is the case, you need to ensure that your web application has write-permissions within the App_Data folder of your website.
It is hard to say exactly without seeing your connection string, but possibly this KB article will help. It relates to SQLExpress and the error you are seeing.

Exising .net 2 app migrated to .net 4 and moved to an IIS7 Windows 2008 R2 server.
We used to be able to run some code on the web page to export some stuff to excel.
Now, when we do... we get the following error:
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {00024500-0000-0000-C000-000000000046} and APPID
Unavailable to the user d"omain\username" SID (S-1-5-21-2084383492-816144152-925700815-4150) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.
Any thoughts?
I did wonder if it may be to do with the authenticated user being on a different domain to the webserver - where we see this error??
Try following this resolution:
Microsoft Support
I believe that the basics of the error are the same. The user you are trying to run the DCOm component as does not have permission to start it.
Restarted the web server and this error no longer appears... I get another error when I try and do the workbook save... I'll post another question on that.
Thanks for your help
We're getting the following error when trying to establish a connection to a database file in the project:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
Any ideas on how we can fix it?
Thanks in advance!
http://jeremywadsworth.com/Default.aspx?blogentryid=56 has one possible fix.
http://forums.asp.net/t/1377174.aspx also has further discussion on the topic.
Hope that helps.

One more idea. I think I've encountered something like this when using Visual studio to create and access my database. You can detach your database file from visual studio and then directly attach it to your SQL server. I can't remember if the problem manifested in the same way or not but this should get you around the user instance issue. If this doesn't apply let me know and I'll see if i can come up with anything else.
If you are using IIS as the server,then this occurs because the server takes default asp.net database.
In IIS server,create your own application pool and run your app on that instead of using the default pool.
Check the permissions.Give full access control rights.
Also,
go to SQL server configuration>properties. Select local system in the built-in app.. And your new pool should also have local system selected.
This fixed the problem for me. Hope it works for someone here.
PS: If you are trying to making connectivity in Visual studio for android application,then close the visual studio before running it on android as the process wont complete if visual studio is open and will result into error.
SQL Express file attach starts a new 'user instance' SQL Server. This involves a new master/model/msdb/tempdb set of files that are created in the user settings data folder. also the startup of the new 'user instance' can take up to several minutes on extreme cases.
This MSDN article on SQL Server 2005 Express Edition User Instances cover in detail the process and luckly it has some Common Issues and fixes. The most common failure is due to access rights over the user settings copied files. You will usualy get details about the failure in your NT event log (ie. why did the child instance not start).
We got over this by copying the database from my machine to my team-mate's.
I am working in visual studio 2008 sp1 and trying to publish a web site to a local directory. I keep getting the following error :
Error 3 Access to the path 'C:\Users\name\Documents\Sandbox\BTNET\App_Data\BTNET.mdf' is denied.
My question is how do I determine what user account Visual Studio is running as? I have tried to give everyone, guests, and IUSR_ full control and I am still getting this error. It’s painful..
You must "run as Administrator" VS2008 and publish site
Bring up task manager (ctrl+alt+delete) and look for devenv.exe.You should see the user in the User Name column.
AFAIK (As Far As I Know), it's ASPNET account
Since you're having problems accessing the DB file, make sure all the connection to that database are closed. That file might be in use, which in turn will cause the error.
It sounds like either an application is open and using the file(i.e. Visual Studio, modifying the schema or data or an instance of Access) or the user publishing the files does not have access to the delete files.
The first scenario is more common.
