Installation problem

I just connect my ssd Reaycache, the bios detects it and W7 64 bits also sees the drive through device manager, but when I start the ExpressCache software installer, the initial screen appears and although pulse “next” nothing happens

Did you scroll to the bottom of the EULA so the next button becomes active?

This isn’ t happening, this isn’ t happening, this isn’ t happening, this isn’ t happening, this isn’ t happening, this isn’ t happening!!!

To clarify the problem:
On the first page of the installation the “next” button does nothing, I can’t go to the next page and accept EULA

You need to scroll to the bottom of the EULA before the next button is active. They want you to actually read it. You do not have to read it but you do have to scroll to the bottom. IIRC it even say scroll to bottom to activate next button or something like that right next to the EULA box. 

To be specific:
When I press “next”, EULA screen does not appear, so I can not do scroll.
The first “next” button is not working, the conditions EULA screen does not appears.
I  tried to install the application on another computer with W7 and it worked perfectly.

could you post some screen shots?
