Hi John,
possibly you have simply changed "too much" in the YEM since the last Pack Installation, so that a QUICK Installation is not possible at this point in time.
The YEM normally "remembers" the status of the last Pack Installation (gray area in the bar). If this is the case, you can add Packs and / or deselect previous contents and then use the QUICK Installation method to bring the Genos up to the desired new status.
In some cases, however, the YEM can get "mixed up", ie "forgot" the last state installed on the instrument. Then you HAVE to do a "Full" Installation again.
If the problem with the QUICK Installation persists, I recommend that you first generate a "Full" Pack Install file (.cpi) and install it on the Genos. In the future you should be able to work successfully with the QUICK Installation method.
P.S.
In my experience, the QUICK method brings a time advantage especially when a relatively large number of Packs are installed. If you only work with a few Packs anyway, it doesn't take much longer with the "Full" Installation.
P.P.S.
You can avoid the whole "clutter" with "Full" or "Quick" Installation if you simply work with the
Wi-Fi method. To do this, connect the Genos to your local Wi-Fi network in "
Infrastructure" mode (your PC must be in the same network of course) and click, if necessary, in YEM on "Install Target > + > Search Instruments". A network symbol should then be displayed on the Genos Install Target button. Instead of creating a Pack Install File, you simply click the "Send to Instrument" button.
Best regards,
Chris
