What is the latest version of Excel you are using for creating User Defined Documents.
I have frigged around with this for a week and bought various copies of Excel to get this working and have come to the following conclusion.
Excel 2016 - No Go
Excel 365 - No Go
Excel 2013 - Have not tried
Excel 2010 - This works.
File Format must be .xls and not xlsx.
Is this correct?
If so, how do your client build their own templates if they have, say, Excel 2016 and you need to run Excel 2010 of the server?
Also seems 64bit version of Excel on the server is no go... Messed around with Tanuki Wrapper and this failed.
So, I thought this was the issue but Excel 2010 32 bit on the server with templates built in Excel 2010 works as expected.
Would be very interested in the experience of others.
Might be time to update all this functionality to a later version of Excel I would hope.
