ADE for Android help

Cada vez que entro, solo me aparece la instalación para Mac or Windows

I ve tried a few times,  but always show  me 2 options: install for Windows or Mac.

Even I've tried with the Windows option,  the program do no install

I dont Know what to do.  Please If someone can tell me hoy to do. I've bought a lot of epubs with DRM protection (*.ascm) because at that moment i didn't have any problem with instaling ADE.

Thanks and sorry about my english.
