After upgrade Joomla to 3.7.2, Virtuemart 3.2.2 shows back-end problems

[AdiM]

Hi, I upgraded a site from Joomla 2.5, and I started with an upgrade of Virtuemart 2 to VM3.2.2 - it looked OK.
Then, I upgraded Joomla to 3.5.1 and further to 3.7.2.
In both cases, Virtuemart is still functional in the frontend,
but in the backend:
- Virtuemart link is missing under the Components menu
- TCPDF and Virtuemart AIO (both 3.2.2 and installed) links in the Components menu lead only to 404 errors.
I can reach the Virtuemart CPanel with the direct link only /index.php?option=com_virtuemart

How can I solve this, if anyone can help?
