progid not found

. What I do wrong because on my computer where I have Microsoft Word this code work fine in NetOffice?

Word.Application wordApp = new Word.Application(); <-- here is this error

Answer 1

NetOffice is just a COM Wrapper to the office applications, therefore it requires that you have the office app installed on the machine where your application is running.

i.e. You need to have Microsoft Word installed on any machine that you intend to run an app that uses NetOffice.Word.

If this was a desktop app, all you would have to do, would be to install Word on the machine, but given you want to use office automation from a server, and Microsoft does not recommend it, you should look into other options of interfacing with Word documents directly via OpenXML without having to install Word on the machine.

I'd recommend taking a look at the DocX library: https://github.com/WordDocX/DocX

As well as the articles below:
