Could not load file or assembly 'Microsoft.SqlServer.Express.Reports, ....

freshly installed SSMSE and upon opening get the following error...

Could not load file or assembly 'Microsoft.SqlServer.Express.Reports, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)

Any ideas how to get past it?

This is really odd. Could you try the following...

1) Uninstall everything you have right now

2) Download the latest version directly from Microsoft

3) Install the latest version
