Invalid index. (Exception from HRESULT: 0x8002000B (DISP_E_BADINDEX))

Hi Stephen,
It looks like you have incompatible assemblies on your machine, which causes this issue. I suggest that you use the following clean-install instructions to fix your installation:

1. Uninstall the products (CodeRush, Refactor & DXCore);
2. Search for any remaining DevExpress.CodeRush~, DevExpress.DXCore~ or DevExpress.Refactor~ DLLs located on your hard drive including your GAC (<Windows root>\Assembly) and delete any if found;
3. Backup your user settings located in the "<Document and Settings>\[YourUserName]\Application Data\CodeRush for VS .NET" folder and delete it.
4. Delete the following Registry Keys:
   HKEY_LOCAL_MACHINE\SOFTWARE\Developer Express\CodeRush for VS
   HKEY_CURRENT_USER\SOFTWARE\Developer Express\CodeRush for VS
   HKEY_CLASSES_ROOT\CLSID{7EB58660-96F1-49CF-B8AF-F47152B8CE29}
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\AddIns\CodeRush
   HKEY_LOCAL_MACHINE\SOFTWARE\Software\Microsoft\Visual Studio{VSVersion}\Addins\CodeRush
   HKEY_CURRENT_USER\SOFTWARE\Software\Microsoft\Visual Studio{VSVersion}\Addins\CodeRush
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\Packages{13041012-50AF-4d13-A1E1-4978B21E49CD}
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\Packages{BD359A86-BF88-4c4e-A7D2-6CDDA36C3B79}
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\Packages{02BD4ECB-C032-4ced-B3C1-51AD29309225}
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\InstalledProducts\DXCore
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio{VSVersion}\InstalledProducts\Refactor!
   where VSVersion is your VS version
5. Delete the DevExpressTools.Addin file from
   <Documents and Settings>\All Users\Application Data\Microsoft\MsEnvShared\Addins
   and/or
   <Documents and Settings>\[YourUserName]\Application Data\Microsoft\MsEnvShared\Addins
   (BTW, you can't use DXCore/CodeRush Evaluation currently published on our web site with the latest Refactor! for VB.NET. If you want to use them, please let me know.)
   If this doesn't help, please do two more things:
6. First run the following command line from the command prompt and post the resulting file here:
   dir /s devexpress* >c:\Result.txt
7. Second, use the instructions from http://diditwith.net/PermaLink,guid,a7ab5b1b-9171-4c7b-8439-8a459651e078.aspx to debug the issue. It may give a call stack, which we can use for further investigation.
   Finally, please specify whether you have any 3rd-party VS IDE add-ins, and whether you are using any 3rd-party realtime system (antiviral/antispyware) protection tools.
   Thanks,
   Max
