Make sure the application for the file type (.vb) is installed


  • I installed VS 2005 Beta 2 on a WinXP pro system (numerous times). It finally installed without erreors. It looks like it is basically working - I can create a new windows project and add items from the toolbox, edit the code etc. If I open an existing project (created on another box) things load properly but I cannot open any forms in designer view (I can open them in code view). When I attempt to open a form in design view I get the following error popup:

    There is no editor available for 'c:\....\myForm.vb'.
    Make sure the application for the file type (.vb) is installed.

    Any thought on how to correct this?

  • Eliminating the signing as mentioned in that other thread seems to have solved the problem. I sure don't understand why?

    Thanks - now I can get back to work

  • This was a bug that was fixed for the release version.

  • I am using vb.net (Visual Studio 2005 version) and get the same message when trying to open a form in designer view.  The message is


    There is no editor available for 'c:\....\myForm.vb'.
    Make sure the application for the file type (.vb) is installed.

    I have tried the suggestions in the e-mail trail with no success.  The problem only occurs in the project I am currently working on and it only started today.  Prior to today, I had no problem.  Also if I open previous projects I have no problem.  Seems specific to the current project set-up.  Appreciate any assistance you may have.

  • I have the exact same problem when I tried upgrading my vb2003 project. Can't open any forms in the designer, even new ones. If I created a new project from scratch, no problem, only on an existing 2003 project.

    It also can't find any of the existing ActiveX controls & servers. If I go back to vb2003, no problems.

  • ok, it turned out it was a missing COM reference, I removed it and VS 2005 works fine now.

    I also had the same problem and have not been able to user VS2005 forms editor for VB since two days ago. I have MS tech support working on it. What exactly did you do?

    Hi Bob,

    I expanded the References + sign under the project, remove the reference with an exclamation mark, save the project. Exit and re-enter the project and everything works fine. Thanks.

  • Desculpem-me por escrever em português:

    Eu estava com o mesmo problema até que tive a feliz idéia de comparar as propriedades dos forms que o VB abria sem problemas com o form que produzia essa mensagem de erro. Conclusão: Mudei a Build Action para Compile e findou-se o problema.

    Veja no link abaixo a figura do passo-a-passo:


    Boa Sorte!
