I’m sorry, I don’t understand the question. If you click on the link above, it should download a SimConnect.zip file. I’ve downloaded it a bunch of times and there is no malware in it. In the zip file are three directories and a readme file. Install the contained simconnect.msi files in the order prescribed by the readme file.
Back in the day, FSX was updated twice, and along with the updates, Simconnect was updated each time. To get it to work correctly, the packages must be installed in order. These Simconnect files do not interfere with the MSFS Simconnect install.
If you have 4, I don’t know if that’s going to work. I can only vouch for the install procedure I used which I outlined in the first post, and I’ve been using it since I wrote it. If you’re going to do other things, that’s up to you.
And you don’t need to apologize for asking questions. You can’t know what you don’t know.
