Library folder + Relocate ensembles

Hello,

I just updated Komplete from 5 to 10 (Mac) and have a couple of questions I hope someone can answer.

1) On completion of the installation process, a “Library” folder has been created in the root folder of the destination disk (an external one) where the Content are being stored; it contains a “Receipts” folder where .bom and .plist files are to be found. Can I delete this folder or must it be kept in place?

2) While installing the Content to the aforesaid disk, I didn’t realize that that would have also included all Reaktor’s and GuitarRig's new stuff; after a (much too) quick look at the service center I thought that they could have been moved elsewhere with no issues, by using the well known “relocate” function after the “No Binary Found” alert in the Overview list. Nope! Ok, I know, it’s clearly stated in the manual that…

Now, the ensembles are working flawlessly, but I fear I could have issues in the case of future updates; nonetheless I want to keep them along with my other ensembles, inside a specific folder on my main disk (this also applies to Guitar Rig extras).

How can I sort the issue? I think there must be a .plist file somewhere that must be modified accordingly, but, should I be stoned if I can find it!

Ah, and while we are at the Service Center, not a vital point, but: it persists in prompting me to update Electric Piano to ver. 1.5.0: how can I get rid of that?

Many, many thanks for your answers.
