FS passanger DLL error

[epza]

Hello I have a constant problem and I'm getting this message "Flight Simulator has detected a problem w/ a third-party software program(add-on):
Do you want to run this software(not recommended)?
To avoid seeing this message in the future, uninstall this program or disable its ability to start
when running Flight Simulator.
I found the FSX registry cleaner program and I don't see the message anymore for at least a few days but there is another problem that my license key is not valid anymore. I already asked the owner of the program ten times to get the new one and it will work until Dll.compatibility error shows up and the story starts again.FSX registry cleaner and the previous key product is not working anymore, again I  have to ask the owner to get new keys, I'm tired of asking for the key product again and again. Is there any solution for it?
Happy landing EPZA

Epza, you can certainly use the search function to find a myriad of answers regarding the issue you are having. Here is one for example:

Once you have enlightened us with more information about the version of the sim you are using, which directory you installed it, and the pertinent information you can provide us that is contained in the log.txt and install log files (within the main FsP folder), then we can move forward.

In addition. On Windows 10, due to any Simconnect or FSUIPC crash, raised maybe by some other installed add-on, it could happen that the FSX registry will be corrupted. In this case, to re-align any FsP registry settings, it's possible to just run the FsPassenger installer, without installing it. The installer, on startup, checks fo any registry error and corrects it. So, after the correction massage just close the installer. At the first FSX run, it will ask to agree about the FsP addon execution.
