"No Error" pop up message when opening VMware, BMR or other plugins from the Backup window

NVBU 9.x Hybrid build is successfully installed on 64bit Linux RHEL 6.4.
The latest Hybrid VMware plugin and BMR are also successfully installed.
However any attempts to open the plugins for configuration from the Backup window, return the following pop up message:
----
No Error.
----

Trace on the gui process shows that the NVBU server cannot contact the client to launch the plugin process:
----

Finally, if the Pure 64bit NVBU build is installed on the same machine together with the 64bit VMware plugin version, the plugin can be opened and configured without issues.
However, since the BMR plugins are only 32 bit, the Hybrid NVBU build must be installed on this machine.

This type of issues are almost always caused by required libraries missing in Linux.
In this particular case the libz.so.1 library was missing from the /lib/ folder, although present in the /lib64 as this was a 64 bit OS.
The libz.so.1 library is part of the zlib.i686 package and is not installed by default on RHEL 6.4 and must be installed in order to allow some NetVault 32 bit applications to function on 64 bit OS.

1- First check that all necessary libraries needed by the plugin, here VMware plugin, are installed:

#> ldd <NV_HOME>/bin/nvvmware

Check for any "Not found" or "Missing" statements on the right side of the =>
In this case we could see :
libz.so.1 => not found

2- Install the missing library:
'yum install libz.so.1' should fix this issue.
After installation the libz.so.1 library should be present and linked in the following folders:

[root@rhel64 lib64]# ll /lib64/libz*
lrwxrwxrwx. 1 root root    13 May 14 10:56 /lib64/libz.so.1 -> libz.so.1.2.3
-rwxr-xr-x. 1 root root 91096 Oct  3  2012 /lib64/libz.so.1.2.3

[root@rhel64 lib64]# ll /lib/libz*
lrwxrwxrwx. 1 root root    13 May 14 13:12 libz.so.1 -> libz.so.1.2.3
-rwxr-xr-x. 1 root root 75384 Feb 21 23:01 libz.so.1.2.3

3- If the ldd output does not show any missing library, then look at the dynamic VMWare libraries folders structure to see if anything is missing:
These folders should have the following structure:

#> ls -lR <NV_HOME>/dynlib/vddk

If anything is missing or is different than the above, please remove and re-install the plugin and verify the issue is fixed.
