Applies to: Visual Basic 2010 ExpressVisual C# 2010 ExpressVisual C++ 2010 Express


You try to open Microsoft Visual Studio 2005, Microsoft Visual Studio 2008, or Microsoft Visual Studio 2010. However, the Visual Studio development environment crashes.


This issue occurs when the system registry contains incorrect information for the IServiceProvider interface. An application installer may have registered this interface to an incorrect proxy/stub dynamic link library.


To resolve this problem, enter correct information into the registry by registering the Ieproxy.dll manually. To do this, follow these steps:
  1. Click
    StartStart button
    , type
    in the search box.
  2. In the results list, right-click
    , and then click
    Run as administrator
    to start an elevated command prompt.

    If you are prompted for an administrator password, type your password.If you are prompted for confirmation, click
  3. For 32-bit operating systems, run the following command:
    regsvr32 "c:\Program Files\Internet Explorer\ieproxy.dll"
    For 64-bit operating systems, run the following command:
    regsvr32 "c:\Program Files (x86)\Internet Explorer\ieproxy.dll"

Note This issue was first reported for an operating system that is based on Windows 7. The resolution was tested fully on this operating system. If you are running other operating systems, this resolution may not work. Specifically, if Windows Internet Explorer 8 is not installed on the computer, the proxy/stub dynamic link library for the IServiceProvider interface will be Actxprxy.dll instead of Leproxy.dll.
