I tried the Excel Fuzzy Lookup add-in available here:

http://www.microsoft.com/en-us/download/details.aspx?id=15011

The target PC has .NET Framework 4.5.2 up to date as of 04 JUN 2015, and the Visual Studio Tools for Office (VSTO) runtime v4.0 installed.

I followed the installation instructions and had it installed for All Users, and then I understand each user needs to open the .vtso file supplied to add the add-in to their Excel profile. That's fine, except the .vsto script complains that I am missing Microsoft.Office.Tools.v4.0.Framework.dll. There are other .NET DLLs in the same folder as the script, so even with the VSTO v4.0 Runtime installed I'm guessing this thing needs to add other components.

I found a set of v4.0 DLLs from a co-worker's installation of Visual Studio, so I copied those into the installation folder, but then the .vsto script complains that the tools framework v4.0 DLL doesn't have the same hash. That must be to make sure I have the right version of the DLL, which I apparently don't.

Even with this, the add-in is available for use, though it locks up after a while doing matches.

I'd like to find the right versions of these components.

So I don't need to run the VSTO file for each user? I guess that made more sense, though the instructions were clear that you had to run that for each user that wanted to use the Fuzzy Lookup add-in.

I wonder why the installer had an option to open the installation folder on exit.

OK, thanks for clearing this up.
