Access VBA MailMerge.OpenDataSource

[atlasinformatique]

I use Word Mail Merge from Access VBA with the command
wdapp.ActiveDocument.MailMerge.OpenDataSource
I do not understand why the command works well on a computer and not on a other computer
Indeed the MailMerge.State status is 0 when it is OK and 2 when it is KO
How to find documentation to test the technical background between two computers?

do they have the same OS?
do they have the same WORD version?
do they have the same ACCESS versions?

it is not the same OS, not the same WORD and not the same ACCESS but the same file access .accdb
