First you need to obtain the vmdk files from the Soul Dev Team.
They are located here - > Link
Once you download everything you need, you will need to copy the unlocker files to the ESXi box.
Navigate to OS X 10.8 Mountain Lion Retail VMware Image\VMware Unlocker - Mac OS X Guest\VMware 8.x Series\VMware ESXi Unlocker
You need to copy the Unlocker.ESXi and the install.sh.
If you don't already have SSH enabled here is how you do it -> Link
Next SCP the files (replace x.x.x.x with your IP)
If you are using OS X
scp -v Unlocker.ESXi email@example.com:/tmp
scp -v install.sh firstname.lastname@example.org:/tmp
If you are using Windows I suggest you use putty(Link)
C:\Program Files (x86)\PuTTY>pscp.exe "Unlocker.ESXi" email@example.com:/tmp
Now SSH to the ESXi box.
Type: cd /tmp -> Enter
Type chmod 777 * -> Enter
Type ./install.sh -> Enter
Run VMware converter (Link)
Boot up the vm and go through the installer
You need to remove the network adapter and add another one. This time it will pull a dhcp address.
You need to install the update fixer and then apply the latest patches. Now at this point vmware tools will install correctly.
