Have installed the OEC (Open E Cry) Excel add-in and it works on this system: Win 7 (32 bit), Excel 2013 (32 bit). Would like to get it working on another computer (Win 10 or Windows Server 2012), and have tried many versions of Excel, but the add-in does not appear in the add-ins list. Nobody seems to know anything about this add-in: What are the system requirements? It is possible to transfer the add-in? Does someone have the add-in file (I only have the .exe installation file)? Any help will be appreciated.
If it involves the excel RTD function then you are out of luck. That function does not work on a windows 10 machine period. I have tried to make it work on Windows 10 - I tried various versions of Excel from 2007 to 2016 and I tried the 32 bit and 64 bit versions of Excel - no luck.
RTD is a function that enables Excel to do DDE. It uses a COM addin that is no longer supported or functional in Windows 10.
