Cant open trial version of Toon Boom Harmony Premium on mac

I was trying to open Toon Boom Harmony Premium for the first time after installing the trial version on iMac
And on the very first start the error message pops up saying:

Dyld Error Message:
Library not loaded: @executable_path/…/…/…/tba/macosx/lib/libOSGBase.dylib
Referenced from: /Volumes/VOLUME/*/Harmony Premium
Reason: image not found

And app crashes

Additional data:
Date/Time: 2017-01-24 12:13:11.517 +0200
OS Version: Mac OS X 10.12.2 (16C68)
Report Version: 12

What’s really strange about it is that Advanced version starts and works just fine, but I really do need IK bones
so what should I do?

PS No restart doesn’t help

Try deleting the installation, redownloading and installing another the Trial.

Could be that some files didn’t download properly.
