Can't Install Adobe CC Applications to Removable Drive. Why?

Hi all,

I've tried to install my Adobe CC applications to a removable drive by changing the default Adobe CC application installation path to my microSD card path, but I get an error saying Adobe CC applications cannot be installed to removable drives.  I then tried various workarounds I found on the forum that worked for some people in the past, but they now seem to have been blocked by Adobe on the later releases of Adobe CC.  It's incredibly frustrating for large apps to block installation to removable drives as I, like many people, only have limited local disk space.  I have plenty of other applications installed that are able to run on removable drives.

My question is to any app developers out there is what are the technical reasons that Adobe is blocking users from installing their apps on removable drives? Is there a legitimate technical reason for it (e.g. to prevent licensing issues) or are Adobe just being lazy/difficult at finding a solution? I read somewhere that the apps use the system registry on the local drive and if the removable media is blocked, the registry could become corrupted.  This sounds a bit far fetched to me as I have a standalone version of Adobe PS 2017 CC installed on a removable drive and it works perfectly.  I can't imagine the apps are constantly read/writing to the registry, presumably only at launch and exit.

Thanks

Paul
