Hi,
I have been trying to load Silverfast 6 on to my Mac Pro running Mavericks but just get the message "Silverfast Installer quit unexpectedly". I tried it on my iMac (also running Mavericks) with the same result. Just tried it on my old Macbook Pro running Lion (non intel mac) and it appeared ready to load ok. I don't want it on the Macbook so didn't proceed as I don't want to waste the registration of the software. Is there any way I can run it on my Mac Pro with Mavericks?
Many thanks, IanB.

Dear customer,

your version of SilverFast 6 unfortunately does not support the operating system you tried to install it in.
Please upgrade to the latest version of SilverFast 8.0 if you want to use it with OSX 10.9.

To learn pricing for an upgrade, please go to our website, follow the "Store" link, and proceed your purchase as if you'd wanted to buy a new product.

Please note the sentence next to the product selection: "If you already got a SilverFast product, you might be eligible for a discount price for a new version by clicking here."
Follow the instructions and keep the serial number for your current product ready to calculate the upgrade prices.

Thanks for your interest in our software products.

Kind regards,
Arne Ketelhohn.
