Thanks for your answer. After ages the support answered and told me that Padshop Pro 2 is only for Windows 10.
When I bought Absolute 4 it said that 64-Bit Windows 7 / 8.x / 10 is supported. No direct info that this does not apply to Padshop Pro 2. Only when you call up the Padshop Pro 2 page, you can see this. Unbelievable.
