Install RoboHelp 9.1 on Windows 8 64 bits

[jeanha]

When I try to install RoboHelp 9.1 on Windows 8 (Pro) 64 bits, I got an error message saying that the installer is not compatible with Windows 64 bits. I using the compatibility mode did not helped.

I wonder if there is a way to install RH9 on W8.

Thanks in advance.

Only RoboHelp 10 has been tested against Windows 8 and even then only on a final beta build. RoboHelp 9 is at least two years old and so could not have been tested on a Windows 8 setup.
