HI,
Just installed RadStudio 12.3 on a clean empty VM with latest updates.
Then installed SubscriptionManager and started to install all BIZ components.
Lingering bug since 12.2, starting with Business Core Library (and all BIZ components), it tells that Android is not installed, which of course is wrong.
Just like with 12.2, this bug can be worked around by still checking Android On, bypass the warning, and it compiles.
That's a known issue, indeed the workaround is to check Android, ignore warning and proceed. And this will not be fixed, since it's the old installer.
For now and one, please use TMS Smart Setup to install BIZ products.
