SQL Server 2012 Analysis Services Deployment Wizard broken after SP1

Question

I have installed SQL Server 2012 SP1, now I cannot edit Data Source Connection Strings anymore in the Deployment Wizard.
When clicking the button labeled "..." I get an error "Could not load file or assembly 'Microsoft.Data.ConnectionUI, Version=8.0.0.0' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference".
This happened on two different 2008 R2 servers and local windows 7 desktop, SP1 Cumulative Update 1 does not fix the error.
Please help!

Answer 1

I managed to fix it by modifying the Workaround from Microsoft a bit.
Microsoft Fix: https://support.microsoft.com/en-us/kb/2809127/
Summary of fix:
Open the following configuration file in a text editor, such as Notepad, as an administrator:
<var class="sbody-var" style="box-sizing:border-box;"><system drive>:</var>\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\Microsoft.AnalysisServices.Deployment.exe.config
2. Insert the runtime XML tags after the </startup> tag in the configuration section:<configuration>
<startup>
<requiredRuntime version="v4.0.30319" safemode="true" />
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.Data.ConnectionUI" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="8.0.0.0-9.0.0.0" newVersion="10.0.0.0"/>
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Microsoft.Data.ConnectionUI.Dialog" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="8.0.0.0-9.0.0.0" newVersion="10.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
What i did to make it work:
<configuration>
  <startup>
    <requiredRuntime version="v4.0.30319" safemode="true" />
  </startup>
  <runtime>
                <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
                                <dependentAssembly>
                                <assemblyIdentity name="Microsoft.Data.ConnectionUI" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
                                <bindingRedirect oldVersion="10.0.0.0" newVersion="8.0.0.0"/>
                                </dependentAssembly>
                <dependentAssembly>
                                <assemblyIdentity name="Microsoft.Data.ConnectionUI.Dialog" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
                                <bindingRedirect oldVersion="10.0.0.0" newVersion="8.0.0.0"/> 
              </dependentAssembly>
                </assemblyBinding>
   </runtime>
</configuration>
Instead of redirecting from version 8 and 9 to 10, i reverted it and made sure it uses version 8.
