Hi, everyone,

I try to install CFX5.6 in my machine in which the window NT 4.0 pack 6 is used. There is no any problem in the process of installation. After that, I can use the CFX-Build, and solver looks good. But when I start the CFX-pre or CFX-Post, the same warning message comes out: CFX-Pre or CFX-Post exits with return code 2. Who knows what this mean? What happen in the installation? because of the software or hardware? Please give me some idea!

Thanks a lot.

Hannah

Hannah,

We installed on NT and have had no problems. It's most likely a problem with your system.

Hi HANNAH LIANG! Is your computer connected to networks?

Hi, thank James and Miko. Yes, my machine is always on the line. The CFX5.5.1 works very well. The CFX-Build and solver are OK.

Hi,

There have been a number of cases like this, where CFX-Pre or CFX-Post fail to start, and they all seem to be related to a hardware graphics problem on Windows.

The workaround is to reduce the hardware acceleration on your machine. Go to the 'Control Panel / Display / Settings/ Advanced / Troubleshoot' section. Reduce the hardware acceleration by moving the slider to the left (try half way).

This should fix the problem.

Good Luck!
