That's preferable if the SR2 patch will include everything in SR1, like what was done in the past with Poser 4 Pro Pack. However, the email does not read that way to me when it says "Due to the inclusion of the additional patch..." I'll try installing SR2 without SR1 and see if it asks for SR1. It would seem that if SR2 is smaller than SR1, then SR2 is missing something. Or would I need to obtain the character updates separately?

Poser 2, 3, 4, 5, 6, 7, 8, 9, 10, Pro 2014, 11, 11 Pro
