Package 'ElementHost Designer Package' has failed to load properly

Question

I am receiving the following message:

Package Load Failure

Package 'ElementHost Designer Package' has failed to load properly (GUID - {7EAB3C71-59ff-4571-A5F3-643F255FC2E6}). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading.

My environment is:

Windows Vista Ultimate

Visual Studio 2008 Version 9.0.30729.1 SP

.NET Framework 3.5 SP1

ASP.NET MVC framework (1.0)

This error is triggered by initializing the ToolBox view in Visual Studio.

TIA,

Randy

Answer 1

Hi Randy,

Sorry for delay.

Could you please try running "devenv /setup" and "devenv /resetskippkgs" (in Visual Studio 2008 Command Prompt) in order to see if the problem persists?

Hope this helps. If it doesn't work, please feel free to let me know.

Best regards,
Yichun Chen

Answer 2

It appears to be working properly now - one observation that may possible be noteworthy:

First, I logged in using an administrator user account. Next, I ran "devenv /setup" and "devenv /resetskippkgs". Then I launched Visual Studio. I received the same error message: "Package 'ElementHost Designer Package' has failed to load properly".

I logged out of the admin account and logged in again using my limited user account. Then I launched Visual Studio and the toolbox worked.

The lesson to learn here may be that I had to launch Visual Studio twice after running "devenv /setup" and "devenv /resetskippkgs" for the package to load properly.

Thank you!!!

Answer 4

I'm having the same problem, and trying the two devenv commands is having no effect.

I've also tried to reset the toolbox, but it hasn't helped.

Is there an additional step I can take?

Thanks.
