HI @MSOAdmin,
You do not enable AnyConnect license directly on FPR1010 running ASA image. If you check 'show version', you'll notice that AnyConnect is already enabled. You are required to purchase license still, but, in this case, it will come as right to use.
You only license Standard, StrongEncryption and SecurityPlus features.
You can find this information in Getting Started Guide.
BR,
Milos
