I take it, it is not yet compatible with V2.2.
It is, of course, but you must use the latest Stand-Alone Addon Manager.
I tried my latest installed which indicated that P3D V2.0 or V2.1 was required.
If you mean "installer", then yes, you need a new installer if you want to re-install it, because the previous installer doesn't support 2.2.
If, instead, you really mean "installed", then your installed copy of CYVR doesn't need to be reinstalled, you only need to download and install the latest Stand-Alone Addon Manager.
I downloaded again from the PCAviator and the version on there site was even older that the one I had.
Always download from our site.
We asked PC Aviator several times NOT to host our downloads, which doesn't make any sense since they are always freely downloadable here, and we keep updating them, and this will confuse users.
I also tried to install the later one with the Estonia Tool but it clearly didn't work the gound textures showed and the gates
but non of the buildings 
Never, ever, use that tool with products that supports P3D natively, because you obtain the opposite results: nothing will run, because the product that natively supports P3D (so it needs to recognize it), can't recognize it, because that tool will force it to appear as if were FSX.
An idea when there will be a V2.2 installer?
It's already online since last week.
Again, as discussed in several other threads on this forum about the P3D 2.2 patch, you either:
1) Download and installa ONLY the Stand-Alone Addon Manager, if you simply upgraded to 2.2 WITHOUT Uninstalling the scenery, and were greeted by the Addon Manager warning that the sim version was wrong.
OR
2) Download the full scenery installer, if you Uninstalled the scenery, because the old installer won't allow you to install into P3D 2.2. No need to upgrade the Stand-Alone Addon Manager afterwards.
