Problems with Windows 10 installation
Hi, I tried several times to install Xpress Optimization (Community License) on my Windows 10 machine.
At the end of istallation, it always shows the message "Failed to create new ssh key for Mosel Server. Someone knows how to solve the problem? I noticed that my sistem is "32-bit operative system, x64bit based processor". I think the problem is that Xpress requires a 64 bit operative system...

There are 32 and 64bit versions for Xpress on Windows. For your configuration you need to install the 32bit version of Xpress.
The message that you are reporting occurs during the installation of the Mosel server xprmsrv : what output do you see when you enter this command at the command line (test of the xprmsrv setup):
xprmsrv -tc
Also can you please try (this is the command that seems to be causing the error for you):
xprmsrv -key new
The Mosel server xprmsrv is only used for distributed computing and by Xpress Insight - for standard use of Xpress Workbench + Mosel + Xpress Solvers it is not needed.
The FICO® Xpress Community License (http://subscribe.fico.com/xpress-optimization-community-license?utm_medium=optimization-homepage&utm_campaign=Community-License-Opti-Homepage&utm_source=FICO-Community) is now also available for Windows 32 Bit. Since you have a 32 Bit Windows, you need the 32 bit version of Xpress.
