Dear Office experts and fans,


this question may sound broad, but I have a particular problem and I cannot find the answer nor exact question.

- I have a simple VBA code .Documents.Open ("... web-file ...")
- almost all combinations work - eg. Word 2016 32-bit + HTTP, Word 2016 64-bit + HTTPS, Firefox / IExplorer + HTTPS (all same IP)


- but Word 2016 32-bit + HTTPS is not working - VB throws "File does not exist"
- the provider has confirmed to me that the request has the status of 200 - OK from Microsoft Office Existence Discovery i.e. Word makes successfull request, server gives the file, but Word 2016 32-bit simply can't see it

Obviously, only Word 2016 32-bit has problems.


This is not the first time some office app 2016 32-bit has behaved like from another planet (eg only in Excel 2016 32-bit it is not possible to use UDF in conditional formatting Visual errors while using UDF in conditional formatting on Excel 2016 32-bit, only in this version it is not possible to change the order of sheets that refer to each other otherwise the worksheet function will crash app.. simply alien stuff)

I need to know what the hell is in it this time. How does opening / downloading files work in Word 2016 32-bit?

Does it use IExplorer - if so, when starts and what is its relationship with MS OED protocol?

Where can I find what this method need from webserver? Which handshake / SSL / TLS options?

How is it possible to have different approach to such a basic feature other than 64-bit of same office release?


Thank you in advance


Mark
