NI GPIB drivers installation error in red's line 6.7

Hi to all.

Here I am getting error while updating NI GPIB 488.2 Drivers in Redhat Linux 6.7 version.Its been giving error as Labpalu.so library is failed to initialise. 

I was installed NI VISA 15.1.1 Version with proper configuration before installing GPIB 488.2 Driver.

My system configuration is 64 BIT O.S of  Redhat Linux 6.7 with 4 GB RAM.

While I am using 1 GB RAM,Its was been installed correctly, but while I am using 4 GB RAM,its been giving error.

Here I mandatorily use the 4GB RAM version.Please give your kind suggestions to make me out of this problem.

Thank you in advance.
