upgrade SilverFast Ai IT8 Studio from v6.x to v8.0

[Flash]

Hello,
I just have purchased the upgrade from SilverFast Ai IT8 Studio (Multi-Exposure) Version 6.5+ (Epson Perfection V750 Pro / GT-X900) -> SilverFast Archive Suite Version 8 (Epson Perfection V750 Pro / GT-X900)
Do I have to uninstall SilverFast Ai IT8 Studio v6.x prior or after to the intallation of the new v8 ? I'm not interrested to have both versions on my system (Win7 x64)
Same question to upgrade HDR Studio v6.x to v8 (when it will be available).
Thanks.

Dear Flash,

it doesn't matter when you uninstall SilverFast 6 because SilverFast 8 is seperate application.
