« That path leads to a different library » message appears when I locate my old EWQLSO Gold Ed PRO X

In Native Access I added the serial number of my old EWQLSO Gold Ed PRO XP Library and it’s OK, I see it in Native Access.
But when I locate it the « That path leads to a different library » message appears. I read the page that shows how to fix it (« Path in invalid » page) but the problem remains, there are no solutions…

Can you help me please?

Note #1: it’s the same EWQLSO Gold Ed PRO XP Library folder I used with my previous MacBook Pro with Native Access and it worked perfectly.

Note #2: I added the serial number of my other old libraries (Symphonic Choirs and Ra) and it works! BUT it works only on Kontakt 6, not in Kontakt 7… Why? I don’t know!
