Z88Aurora works fine without any problems
Install from the Internet as follows: Press App "Internet Explorer", enter the Z88 page > Download > click the correct installer (32- or 64-Bit) > Win 8 wants to know: RUN or SAVE. Press RUN. Z88Aurora will be downloaded, then you must answer at least 3 security questions for executing the installer - and here we go. Then you've got another app "Z88Aurora".
