Symptoms

When trying to run the vmware-config-tools.pl script, you are prompted that no pre-built modules exist for the running kernel.

When you choose to compile, one or more modules fail to compile with an error message similar to:

Unable to make a vmnet module that can be loaded in the running kernel:
insmod: error inserting '/tmp/vmware-config4/vmnet.o': -1 File exists
There is probably a slight difference in the kernel configuration between the set of C header files you specified and your running kernel. You may want to rebuild a kernel based on that directory, or specify another directory.

Resolution

This issue is due to a kernel mismatch. It is not caused by VMware Workstation or VMware Tools. The error indicates that you have a newer kernel installed than the kernel you are currently running.

To ensure that you are running the latest kernel you have installed: do so:

Confirm your current kernel version with the command:

uname -a

Check the current kernel version against the default value for your kernel headers shown by the vmware-config-tools.pl script.

For example:

uname -a shows kernel version 2.6.9-5.EL-i686smp

The script suggests this default location lib/modules/2.6.9-78.0.17.ELsmp/build/include

You are running kernel version 2.6.9-5, rather than kernel version 2.6.9-78

Reboot the Linux machine. At the boot loader screen, choose to load the latest kernel.

Rerun the vmware-config-tools.pl script. Now that you are running the latest installed kernel, the compile completes successfully.
