I have built a NEW/empty Add-in for excel(.xll) 64bit. I am running Win10 on a virtual machine through VMWare, using VS2019, Excel 2013. When I load the Addin I get a not a Valid Add-in error. I was able to convert an old 32bit to 64bit which loaded and worked without a hitch. I matched all the values in Properties, and the code compiles with no warnings or errors but it will not load into excel, Just gives the not a valid add-in error.
When I checked the dependencies, I am missing ext-ms-win-oobe-query-l1-1-0.dll which I cannot find anywhere, but the same was also true for the add-in I converted which loads into excel perfectly.
thanks for the help.
