Hello, Thanks for your report (complete with all diagnostics and screenshots <3)

I put here the error that happened (that i've read in the diag)

System.InvalidCastException: Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: Error loading type library/DLL.

The interop Microsoft library seems to not find any version of Word. Keep in mind that File Converter is only compatible with Word >= 2013, but I assume that your version is more recent ^^.

You can try to reinstall word, maybe it will be detected better. I honnestly don't know what I can do since this code is not on FileConverter side.

I have the same issue. It was working fine for a lot of years. Now I bought Office 365. Then I tried to convert a document again, which didn't work. Updated FileConverter from 1.2.3 to 2.0.2. No change. I had to install Office from their website, as doing so from the Microsoft Store didn't work.

Same issue here. I have used file converted for a few months only but it worked very well to batch-convert word file to pdf. I have a genuine Office 2019 installed and did not change anything lately but now I get an error. I use file converter 2.0.2

Instantiate word application via interop.
