change plan
good afternoon,
I have bought the " lightroom CC plan whit 1 TB"

but when i try to download, the system say me that my OS ( windows 8.1) can't launch the LR CC,
and he proposes to me "lightroom classic CC"
can I change my plan "lightroom CC " with "lightroom classic CC" ?
Or is there a service pack on WIN 8 for "lightroom CC plan with 1 TB" ?
thanks for your time
Sergio
