Netflow Collector installation does not start on Linux

Hi,

We are setting up our initial deployment of Netflow Analyzer EE and have the central server up and working fine.
I'm having big problems installing the netflow collector however. I have tried under centos, redhat and ubuntu, all of the clean-installs and in all cases the installation script won't run properly. I have tried as a normal user and as root and also re-downloaded the software to no avail.

This is what happens when I start the installation:
root@svvpnfc01:/apps# ./ManageEngine_NetFlowAnalyzer_Collector_64bit.bin
InstallShield Wizard

Has anyone else encountered this problem and what can be done to resolve it? I need to get this fixed so we can get our deployment up and running.

kind regards
-Michel
