Visual Studio 2010 Package load errors

My Windows 7 installation on my laptop broke down, and I then had to completely reinstall Windows 7, Visual Studio etc.

Besides it being a long and tedious process it seemed to go fine. But I started to get the following error messages when Visual Studio 2010 was launched:

The ‘RadLangSvc.Package, RadLangSvc.VS, Version =, Culture = neutral, PublicKeyToken = 89845dcd8080cc91′ failed to load

VSTS for Database Professionals Sql Server Data-tier Application did not load

and some other VSTS packages that was unable to load.

I followed the steps described here, and it worked :). The steps are also described below:

  1. Close all running instances of Visual Studio 2010
  2. Install the following MSI packages from the installation CD of VS2010, in the folder  \WCU\DAC
  3. DACProjectSystemSetup_enu.msi
  4. TSqlLanguageService_enu.msi
  5. DACFramework_enu.msi

  1. I have installed Visual Studio 2010 on my D: drive and I got the RadLangSvc package error.

    Now it’s ok. Your solution works perfectly !

    Thanks !

  2. Perfect! It really works.

    Probably you did like me and installed partially VS 2010 without some components.
