I am trying to update to build 507 but get a pop up denying the install which reads, "This update must be installed to your existing biab 2018 or higher folder". I tried J:\ and C:\ with the same results. On (Dec 2) I installed 2018 onto the PGMusic supplied xternal drive from 2015 (149GB) which was written over with subsequent 2016 and 2017 releases. I also moved some xternal drives around on the usb ports which changed directory paths, in addition because of limited space on the 149gb 2015 drive I purchased a 1TB x-ternal, I then copy pasted all data from the 149gb to the 1tb drive which is now J:\ as opposed to the former K:\ I would like to have my current configuration as a default, How do I correct the drive paths without having to to completely re-install the package that I purchased from the PG website? Thanks and Happy Holidays to All
