When installing our Outlook plugin, you might run into an error like like this:

  • "The value of the property "type" cannot be parsed. The error is: Could not load file or assembly "Microsoft.Office.BusinessApplications.Fba, Version=, Culture=neutral, PublicKeyToken=foo" or one of its dependencies. The system cannot find the file specified. (C:\Program Files\Comon Files\Microsoft Shared\VSTO\10.0\VSTOInstaller.exe.Config line 10)"
This issue seems to be a bug related to the Business Connectivity Services which is part of Microsoft Office Professional Plus installation. Microsoft seems to be aware of this issue, too.

Until this problem is fixed by Microsoft, you can work around it by temporarily renaming a file called VSTOInstaller.exe.Config like so:

  • Open Windows Explorer
  • Open the folder C:\Program Files (x86)\Common Files\Microsoft Shared\VSTO\10.0
  • If that folder does not exist, try C:\Program Files\Common Files\Microsoft Shared\VSTO\10.0
  • Rename the file VSTOInstaller.exe.Config to VSTOInstaller.exe.Config.bak
Then try installing fruux again. After the installation rename the file to it's original name again:

  • Rename the file VSTOInstaller.exe.Config.back to VSTOInstaller.exe.Config
