It’s a know problem which has existed ever since the CRJ came out in the marketplace. Some people say it has to do with Navigraph, but I have never been able to update the CRJ, regardless of Navigraph being installed or not. I have to uninstall the CRJs completely, making sure the installation folders are gone and do a full install whenever a new version arrives.
It’s simply a major embarrassment for Mircosoft/Asobo/Aerosoft not to be able to fix this.
This is a CRJ problem, not a general problem, maybe you can clarify this in the title.
