Tip/Trick: Avoid launching 2 instances of IE when using Visual Studio 2005 on Windows Vista

  • Comments 3

I've seen user reports in several forums, where two instances of Internet Explorer get launched when doing F5, CTRL+F5, or View in Browser in Visual Studio 2005 running on Windows Vista.

If you are encountering this issue, taking the following two steps should fix it:

  1. Install the beta version of the Visual Studio 2005 Update for Windows Vista.  The final version of this update is planned to ship very soon, I will post an update to this blog when its available.
  2. Run Visual Studio 2005 with elevated administrative rights.  Even if you are a member of the "Administrators" group on the local machine, applications launched in Vista do not run with elevated administrative rights unless the user explicitly specifies to do so.  To use Visual Studio 2005 with elevated administrator rights on Windows Vista, you must right-click on the Visual Studio 2005 icon and select the "Run as administrator" command as shown below:

However, as you will soon realize, its very easy to forget to do this everytime you start Visual Studio 2005.  Luckily, there is a handy way in Windows Vista to always force Visual Studio 2005 to start with elevated administrative rights.  The following steps describe how to set this up:

1. Right click on Visual Studio 2005 shortcut in the Start Menu and select Properties:


2. On the Compatability tab choose "Show settings for all users" button:

3. In the dialog that is launched, check the "Run this program as an administrator" item:

For those Visual Studio web developers out there using Windows Vista this tip should make the experience mostly pain-free!

  • Hi,

    i think you should make it VERY EXPLICIT that an elevated VS is only needed for stuff like debugging ASP.NET apps (when run in IIS).

    Generally you DON'T NEED an elevated VS (console, winforms apps, cassini etc)....

    You are Microsoft. Think least privilege. Better live it!



  • Thank you Dominick for the comment.

    The specific issue mentioned in this blog -- two instances of IE getting launched on F5, CTRL+F5 occurs both when using IIS, or the built in development server (aka - cassini).

    Installing the VS Vista Update, and running VS 2005 elevated is the only solution to this issue.

    You are right however, in the statement that other activities in VS 2005 like building and debugging a console or windows forms apps can be done successfully w/o needing to elevate VS 2005 permissions.

    Hope this helps clarify.
