Hello Pete! 
	I have the following problem. Since I have my new PC FSIUPC 5 is not recognized after installation as it is, for example, with others. 
	This then results in some errors. My biggest problem is that the TCAS switch in the plane is no longer transferred to the IVAP box when you press the switch. Everything is activated. On my first PC, it was synonymous with no problems. When I start the IVAP installer, I am asked if I want to install a newer version of FSIUPC even though FSIUPC5 is installed.
 
	FSIUPC details:
 
	Installed Version: not installed
 
	Version to install: 4.8.5.3
 
	I wanted to attach a picture to this post but that did not work.
 
	Here is my install log:
