Not much to go on, I would start with:
If name of directory for image= /myvmstuff
sudo chown -R lou:lou /myvmstuff
sudo chmod -R 777 /myvmstuff
change lou to your user ID.
Do not use directories in the root partition. Create a separate directory on another hard drive, if possible. Otherwise, put it in your user directory (/home/lou/vmware)
Lou
