Installation von CS6 auf HP Spectre x360

It might work or it might not.  CS5 and CS6 are on life support. But they can still be activated providing you have the following:
1. original media (disks or downloads) you received at purchase and a way to read them,
2. a legitimate serial number for that version, language and platform (Win/Mac),
3. an older operating system that can support legacy 32-bit apps.

NOTE: Legacy Creative Suite is discontinued & unsupported. Use at your own risk.
