Maybe last note from me on this. Summary and where I ended.
1. Installed Platinum first time from Command Center. It successfully and smoothly installed on my C drive, with no prompts or Advanced install options to ask it to install in a preferred location. My preferred spot is on my D drive.
2. Uninstalled Platinum, no problem.
3. Went into My Accounts on the Cakewalk site, Products, then the Connected Products section at the top in there. Clicked on Platinum. A red Download button appeared. I downloaded the installer. Installed Platinum from that successfully and smoothly onto my D drive. The installer does offer an Advanced button where you can select your preferred install location.
4. Started using Platinum. It's great! Big fan.
5. Update announced for Platinum.
6. I asked in this thread above whether Command Center is smart enough to recognize where you have Platinum installed so you can just update from Command Center. Or, I asked, do I need to repeat the manual install process.
7. It was suggested above that Command Center will work for the update no problem.
8. I then updated from Command Center. Result was that it made a clean, brand new install of everything on my C drive.
9. Uninstalled Platinum (again). This uninstall removed it from both my C drive and the previous version from my D drive.
10. Went back into My Account, downloaded the latest version of the installer for Platinum. The download was smooth. The install to my D drive of the latest, complete version of Platinum was smooth and quick.
11. Platinum now running fabulous.
Wasn't that big of a hassle or inconvenience, just noting this for anyone wondering what happens on the installs if not wanting to install Platinum to the default C drive directory.
