Uninstall and reinstall the product.
If the problem persists, contact Adobe Technical Support for assistance in specifying the error code that appears at the bottom of this screen.
Error: 1.
It's the exact translation as I've seen another thread in those forums about this, but without any answer.
No mismatch on tech specs neither, apart from the Windows version:
Intel i5 3570k
8 GB of RAM (DDR3 1600 MHz)
Windows 8 Pro 64 bit
WD Caviar Black 2 TB - 7200-RPM
Sapphire Radeon HD 7870 2 GB
