SVP aidez-moi!

Hello,

I'm looking for someone (a little computer genius) who would be able to help me.

I have FSX on Windows 10. I disabled Windows Defender (I was advised to do so before downloading).

I download on compressed folder or in downloads.

Here is my problem.

When I upload a new aircraft to Rikooo, I have the compressed file in my downloads or compressed files.

I unzip with 7zip and get a new unzipped file.

Alas, whereas before the installation was done automatically, I now have the following info appearing in a blue window. THIS APPLICATION CANNOT RUN ON YOUR PC;

Or another white window that says: IMPOSSIBLE TO EXTRACT;

Does anyone know what's going on and what I need to do to finally download my planes and be able to fly?

Sometimes, during the download which seems to be taking place, the error code x080004006 appears.

I have tried EVERYTHING in vain so thank you if anyone is familiar with this type of problem.
