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.
