Cause

1. This issue occurs in Linux virtual machines when the /tmp directory is mounted with the noexec option for security reasons
 

2. We can verify this by reading following file on guest operating system: cat /etc/fstab.

Resolution

There are 2 possible solutions

1. Open services.sh for vmware tools: sudo vi /etc/vmware-tools/services.sh
2. Add following line on initial portion of the file(Before "BEGINING_OF_UTIL_DOT_SH"): export TMPDIR=/var/vmtmp
3. Save changes and exit. Create a vmtmp directory: sudo mkdir /var/vmtmp
4. Restart VMware tools service: sudo /etc/vmware-tools/services.sh restart

 

Edit /etc/fstab and remove noexec. Changes to this file requires a reboot

 

Note: Directories, sudo commands and files are specific to Ubuntu guest operating system. This might be different on other flavors of linux
