The correct way to install v2.2 is to uninstall all previously installed versions of this bird, and them make clear installation using the installer from Extedned Download section - maybe some of you have installed the 2.2 without uninstalling the previous ones?
After proper installation i have absolutely no problems with VOR/HSI, although after the first launch of FS after 757 installation it worked only after setting the VOR fq in VC.
