Is the Rapture Pro Multisamples directory location held in the Win 10 Registry?

Sorry for starting yet another thread on what appears to be a common topic but my question is slightly different:
I would like to move the Rapture Pro Multisamples directory to another location having cocked this up during the initial install (don’t ask). Problem is, I can’t find a Win 10 Registry entry for the Rapture Pro Factory samples, only Registry entries for the Dimension Pro (1.5) and Rapture (1.2.2) multisamples directories that I have and which Rapture Pro cleverly found on install.
I thought a simple reinstall from Command Center might do the trick, so I entered the Multisample directory location I wanted when prompted by the install program, but the initial location hasn't changed. So it looks like the initial location must get stored somewhere, and it isn’t updated on a reinstall.
Possibly uninstalling Rapture Pro and then reinstall it giving the correct Multisample directory path this time might work, but I would rather just edit a Registry or RP.ini entry, if one exists.
Any help greatly appreciated.

Thank you Scook for your help, I am all sorted now and have all the Rapture Pro Factory Samples at the location I intended.
Just one more quick question: I have the Dimension Pro 1.5 and Rapture 1.2 sample sets that came with those products already on my workstation and Rapture Pro has found them okay; do I still need to download the D-Pro Part 1, D-Pro Part 2, and the Rapture Classic sample sets from the Command Center for completeness, or are these simply the sample sets that I already have installed, it sounds likely.
Many thanks.

After installing all the libraries provided with Rapture Pro on a new selected multisample directory, can I uninstall the previous version of the softwares (i.e. Dimension Pro and Rapture)? Thank you.
