Interop.Word Documents.Open is null

c# asp.net ms-word asp.net-4.0 openxml

If you are still looking for the answer I have found it just a moment ago for my project.

Open DCOM Config Settings:

Tab Identity, change from Launching User to Interactive User

c# asp.net ms-word asp.net-4.0 openxml

Try this it may help you.

Create a new "Desktop" directory inside of "C:\Windows\SysWOW64\config\systemprofile\"

it works for me after a long long long day searching for the solution.

It seams to be a profile problem.

c# asp.net ms-word asp.net-4.0 openxml

I did the following steps and it worked all right:

Create the desktop folder
Change the DCOM element to login with a specific user instead of an launching/interactive user
Changed the service so it started as the same specific user

Edit on 2019-09-29.Due to a big windows update I had to do the exact progress all over again.
