Fixing ASP.NET debug error 0x8013134b

I got the following error debugging an ASP.NET project earlier today:



Auto-attach to process '[2440] w3wp.exe' on machine '...' failed. Error code 0x8013134b.


The problem was that I had installed .NET 2.0 which had registered ASP.NET 2.0 on the Web Site I was trying to debug.


Fixing it is simple:



  • Run the IIS Manager

  • Right click on the web site with the problem

  • Click the ASP.NET tab

  • Change the ASP.NET version from 2.something to 1.something in the combo and debugging works again

  1. Strangely enough, when i do this my VS 2003 is no longer able to create web projects! Any ideas?

  2. Turns out, i had to run aspnet_regiis -i again from my VS 2003 Command prompt and then do what you told. That did the trick! Thanks!

  3. Awesome...I went through many sites before finding yours with the right fix. Thanks!

  4. Great For me it worked after doing the Following.



    I went to microsft.net\famework\v2.0.*\ in .net Command prompt

    and I uninstalled aspnet using aspnet_regiis -u adn I came to the Version ..\v1.1.4 * that I have to use and there I reinstalled it using aspnet_regiis -i

    After this I followed what u have said...



    Its really a nice tip.

  8. hey guys,



    i got the same error message but i am unable to find asp.net tad on iis manager. i am running both iis 1.1 and 2.0. i would like to switch to 1.1 now but on iis admin after right clicking the web site there is no asp.net tab on properties. could any body help me.

    ReplyDelete
  9. You can switch ASP.NET version from the command line.



    To switch to ASP.NET version 1.1:

    - Go to the directory: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322

    - Run "aspnet_regiis.exe -i" to install ASP.NET version 1.1 for all sites



    You can apply it to specific web sites by running "aspnet_regiis.exe -s siteid". You get more help on the syntax by running "aspnet_regiis.exe" without any arguments.



    To be 110% safe, you can follow the tip by kumaresan and uninstall ASP.NET v2 first:

    - Go to the directory: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215

    - Run "aspnet_regiis.exe -u" to uninstall ASP.NET version 2.something from all sites

    ReplyDelete
  10. Thank you, this was on great help, although it didn't worked for me, I guess it was because I selected 1.1.4322.OtherNumber instead of 1.1.4322.0.



    Anyway I decided to uninstall asp.net 2.0 and re-install ASP.NET 1.1 as mentioned in previous message and it worked fine.



    Thank you all

  12. Thanks for the great help.



    I can now debug after running the following:

    C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>aspnet_regiis -i



    Although now I have problems connecting to my SQL database that normally works fine under ASP.net v2... Any ideas?



    Thanks heaps

    ReplyDelete
  13. Can you post the error message(s) you are getting?



    Did you recompile the application after rolling back to .NET 1.1?

    ReplyDelete
  14. Hey thanks for the help, i have this problem i never noticed that the programmer working on morning shift installed framework 2. shit thats why I recieved some hell 0x8013134b message..

    ReplyDelete
  15. try and see if you have 2 Framework clr installed (ver 2, and ver 1.x), if so the iis is using the ver 2 and the visual.net is using ver 1.x (check inside visual studio at help->about to see whice ver of framework is in use), after i removed the ver 2 it worked just fine.

    ReplyDelete
  16. My VS.net help->about screen says it's still using ver 1.1. I have 2.0 installed on IIS and this is what I want to use. How do I get VS to use 2.0? It's really hard to debug without a debugger.

    ReplyDelete
  17. You have to upgrade to Visual Studio 2005 in order to develop and debug .NET 2.0 applications with VS.NET.



    You can use the -free- .NET 2.0 SDK to compile your application but you cannot debug it with VS.NET 2003

  18. that's pretty gay. thanks man.

    ReplyDelete
  19. Thanks a bunch! I would have never figured it out myself.

    ReplyDelete
  20. The command line tool is great, but does anyone know how to get the ASP.NET tab to show up in IIS?

    ReplyDelete
  21. Hi great blogg to help out.



    Had a lot of problems with it. The only way I was able to fix this was to unregister clr2 and register clr 1. Bit of a pain considering the amount of time wasted trying to figure this out.



    The only question remaining is how do you use the two without having to constantly unregister one and register the other.



    After unregistering 2 and registering 1, I also did an iisreset as listed above and I seem to be back in action.



    Thanks again.

  28. Thanks for this tip. I too had spent a day and a half reading thru different NewsGroups. What got me into trouble was my anxious attemp to try and convert a VS2003 .Net appl to a VS2005 appl. The conversion went fine. Little did I know what was actually happening in the background. When I tried to return toi the VS2003 appl, I started to receive this 'Auto attach to process . . .' error message. I did some snoopying and decided that the folder in the c:\inet\wwwrot\ folder might have been causing my problem, so I saved this appl folder for the VS2005 appl in another location and rebuilt the VS2003 small application. NO LUCK, I got the same error message. I was bound and determined to not let this get me down. A stroke of luck thru Google led me to your solution. Thanks for this solution. . . .Tom J.

  50. anyone please help



    I uninstalled v2.0 and v1.0 and then installed v1.0 and then reset iis. but no success for me.



    Am I doing anything wrong??



    I can see the four versions:

    v1.0.3705

    v1.1.4322

    v2.0.40607

    v2.0.50727



    aspnet_regiis -u in all 4 and then used

    aspnet_regiis -i in v1.1.4322 directory and no success at all.



    Plz help?

    ReplyDelete
  51. Thank you so much



    I have tried every way but this very simple



    Thank you "" (^_^)

    ReplyDelete
  52. Thanks a lot



    I simply uninstalled v2.0.50727 and then intsalled v1.1.4322

    Although the ASP.NET tab disappeared from the Properties of Default Web Site in IIS but debugging is working fine.



    Thanks

    ReplyDelete
  53. VS2003 does not support debugging for ASP.NET version v2.0.50727

    So you have to uninstall this and install some other version lower than this.



    Also under ASP.NET tab in properties of the Default Web Site you have to select the proper version.

    It will surely work.



    Thanks

    ReplyDelete
  54. Yeah. I have the same problem. Thanks very much!

    ReplyDelete
  55. I did exactly what you said and it worked. Thanks!

    ReplyDelete
  56. Thank you - this post saved me time (I need to get a PayPal account!). I installed VS Express 2005, then VS 2005 (trial), then removed everything and installed VS 2003 (which we actually have the license for). IIS was still pointing to .Net 2.0 paths, and the suggestion did the trick. Breakpoints are now active.

  57. Wow, thanks a lot. I was trying a lot until I found this tip. Thanks again.

  62. A few questions to help you figure out what the problem is:

    * Do you get "file not found" errors for all files or only aspx files?

    * Do you have more than one web site configured?

    ReplyDelete
  63. OMG it works!

    I didn't uninstall .NET 2.0. Just pick ASP.NET 1.1 for my application in IIS properties.

    I think VS 2003 not going to support .NET 2.0?

    ReplyDelete
  64. Correct; Visual Studio 2003 does not support .NET 2.0

    ReplyDelete
  65. the framework 2.0 could be the reason???

    my app is dev in vs2003 with crystal reports for vs203 but in the server production (win2003s w framework 2.0) the reports don't display the data...really don't display anything...



    thanks 4 your help again!

  68. Another comment to "A" (9/13/2006 3:54 AM)



    You will get "File not found" errors if the web site is configured to use ASP.NET version * on a site but you have not enabled ASP.NET version * in the IIS Manager as a "Web Service Extension"

    ReplyDelete
  69. Ivan; a few questions to identify your problem:

    - which version of ASP.NET did you unregister

    - which version of ASP.NET dir you register

    - which version of Visual Studio are you using?

    - which version of ASP.NET is configured in the "ASP.NET" tab in the IIS Manager for the web site?

  81. Hi timmy.

    Are you member of the "Debugger Users" group on the server? You can verify by running "Computer Management" and going to:

    - System Tools

    - Local Users And Groups

    - Groups



    Check if you are member of the group "Debugger Users"

  84. I have same identical problem as described. When i press F5 in VS.NET 2003 web application, i get : "Error while trying to run project: Unable to start server. There is no managed code running in the process. In order to attach to a process with the .NET debugger, managed code must be running in the process before attaching", and in the Output window I get "Auto-attach to process '[1520] aspnet_wp.exe' on machine 'SV' failed. Error code 0x8004000e.



    I followed the exact steps with aspnet_regiis -u and -i and still get the same problem. Now even got so far as uninstalling .NET framework 2 completely. Still get same error.



    Another strange thing is that when i try to browse the site from IIS (right-click on website and Browse), I get error HTTP 403: "This error (HTTP 403 Forbidden) means that this program was able to connect to the website, but it does not have permission to view the webpage."



    This doesn't happen to all sites, but it happens to any NEW ASP.NET project that I create from VS.NET 2003.



    Wasted a whole day already on this! What could be the problem!

    ReplyDelete
  85. The problem is the "HTTP 403 Forbidden" error. The ASP.NET application is not able to run so Visual Studio is not able to attach to the process.



    Have you verified the security on the directory where your site is created? The account used by ASP.NET to run the site must have read access to the directory.

    Are you able to browse static contents on the site (html, gif, etc)?

    ReplyDelete
  86. Apparently the HTTP 403 error when trying to browse the site from IIS was due to not having specified a default.aspx page, because once i did that it was ok.



    However I still can't debug because of the same error: "Error while trying to run project: Unable to start server. There is no managed code running in the process. In order to attach to a process with the .NET debugger, managed code must be running in the process before attaching"



    Same kind of error pops up when try to manually attach to aspnet_wp process.

    I've put all users (my user name, ASPNET which runs the aspnet_wp process, and the rest of the users created by ASP.nET) into the Administrators and the Debuggers groups to make sure it's not a problem of security.



    Thanks

    ReplyDelete
  87. first thing ur error is different from the original post. so trying same solution is not the exact way. second, do u change ur IP, if so thats a big headache.

    thirdly try running services from Administrative Tools->Services and restart application.

    But first of all check for the correct solution, by googling, (as u'll get a variety of solutions), posting exactly ur Error Code, not similar message or similar error code.
