I reinstall the stand alone manager lastest Stand-Alone Addon Manager without success... Try to rreinstall the last scenery of zurich too, nothing better...
That message did not say to reinstall Zurich. The message says to reinstall only the Stand-Alone Addon Manager, and that would have solved the problem.
BUT I finally found a solution, I installed your last scenery as trial (Hawaiian airport) AFTER installation of Zurich and Geneva, and then it works good....
There's no difference whatsoever to the installation of the Stand-Alone Addon Manager, and the Hawaii scenery. They contains the same files, the only difference it's the Stand-Alone Addon Manager doesn's include the scenery.
So, if you just installed *only* the Stand-Alone Addon Manager, as the message said, it would be exactly the same. And yes, you need to install it AFTER all the sceneries.
Which should be the norm since, if you simply followed what the message was asking, which was to install only the Stand-Alone Addon Manager, you were already with sceneries installed, and that would be the last program you installed anyway.
The issue is, the Addon Manager needed to update some files in the sceneries which were outdated but, it can't obviously update a scenery that is not installed, that's why you need to install it after all the sceneries.
The issue is most likely that you launched the Addon Manager installation when one of your sceneries wasn't installed so, it didn't get the chance to be updated. Instead, you probably launched the Hawaii installer with all your sceneries installed, so they were all updated, just as they would be if you launched the Addon Manager Stand-Alone installer.
but installation process is not as stable as it must be! I ever have problem with installation of Geneva and Zurich.
The installation process works perfectly, if you follow all the instructions and warning messages to the letter. In this case, you only had to install the Stand-Alone Addon Manager without doing anything in between, like uninstalling something else.
Note that, this never happens normally: it's just that we had to do a major upgrade to the Couatl program, which is needed for many reasons, one of them being exactly what you are asking: making it more reliable, and also because we added lots of features that we'll use in the upcoming product, like sound (your .dll error message was related to a sound .dll missing).
Unfortunately, we couldn't update it without being 100% backward compatible with all the older sceneries THAT'S why you saw that message. The alternatives were:
1) keep everything not updated, and losing the chance to improve the product and make it more reliable.
2) updating it and improve it, making it more reliable, at the small cost of having that message popping only ONCE, alerting users with older sceneries to upgrade.
