Visual Studio 2010 - Microsoft.Data.Entity.Design.BootstrapPackage Load Error

If you see the following warning, it means that there is some problem with your VS2010 installation. I believe I encounter this simply because I uninstall VS2010 after my first fresh install.

Regardless the reason, general fix is to uninstall, remove some registry and reinstall. This is a tedious process!!

I tried the following method and work for me to save some time

1. Open Register Editor, regedit

2. If you are 32 bit Window, remove the following

a) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\AutoLoadPackages\{adfc4e66-0397-11d1-9f4e-00a0c911004f}, locate and remove the REG_DWORD {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB}

b) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\AutoLoadPackages\{93694fa0-0397-11d1-9f4e-00a0c911004f} , locate and remove the REG_DWORD {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB}

c) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Packages\{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} and delete this key

3. If you are 64 bit Window, remove the following

a) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\AutoLoadPackages\{adfc4e66-0397-11d1-9f4e-00a0c911004f} , locate and remove the REG_DWORD {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB}

b) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\AutoLoadPackages\{93694fa0-0397-11d1-9f4e-00a0c911004f} , locate and remove the REG_DWORD {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /f

c) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} and delete this key
