I am using Excel 2013, I have installed fuzzy lookup, it got installed without any hassle but it doesn't show up in Excel.

Load behavior of fuzzy add-in in COM Add-ins shows "A runtime error occurred during the loading of the COM Add-ins."

If I try to run Add-in then I get following error:

"The common language runtime could not be loaded by C:\Users\Vicky\AppData\Local\Apps\Microsoft\Fuzzy Lookup Add-In For Excel\Bin\FuzzyLookupAddInForExcel.vsto|vstolocal. Contact your administrator for further assistance."

Hi,

Based on the error message, this issue usually occur with fuzzy lookup not installed completely. Would you like to tell me where did you download the add-in? I tested to download here and installed/worked well in my local environment ( Windows 8.1 64bit and Office 2013 32bit). If you did not download from here, please try this installation copy.

Then, if you were also download with above link, I recommend we clean-remove it and re-install it with Windows clean boot.

Please Note:

• Uninstall any previous versions of Fuzzy Lookup Add-In for Excel. Folder path:

C:\Users\username\AppData\Local\Apps\Microsoft\Fuzzy Lookup Add-In For Excel

• Right-click Setup.exe and Run As Administrator.

Hope it's helpful.

Hey George

Thanks for replying. I have downloaded from the link you gave with the steps you mentioned, but still the problem persists.

I tried installing add-in on Microsoft Office Professional plus 2010 and I am getting the same error.

Hi Sir,

Sorry for replied delay, based on the error message, this issue also might be due the develop environment not installed completely.

Please try to upgrade/ repair the .NET 4.5 and VSTO 4.0 to test.

Regards,

George,

thanks for your help... but I have the same problem as Vivek and I can't fix it. I uninstalled Fuzzy Lookup, installed .NET and VSTO, reinstalled, rebooted, and I still get the error.

VSTO from here: https://www.microsoft.com/en-us/download/details.aspx?id=17375

and Fuzzy Lookup from the link you provided. :(

I am running Windows 8. Maybe that's part of the problem. I tried running the NetFxRepairTool; it found and fixed two issues but nothing changed.

You there, George?
