Can't update Z3ta+ from 1.5 to 1.5.3

I downloaded the update for Z3ta+ to bring it up to 1.5.3, and in the instructions it says to uninstall it first from Add/Remove programs, and then run the updater, but Z3ta+ isn't listed in there to be able to uninstall. I did see DimensionPro listed there, but not Z3ta+. I have Sonar Producer 8.5, and installed everything that was with it. 
 
It is installed, and works inside of Sonar, and with Tobybear's Minihost, but is there a different way to uninstall it?
I am trying to install Limeflavour's Modern/Retro skin for it (which is pretty cool by the way ), and wanted to make sure it's updated first.
 
Thanks for any help 
 
 
P.S. Here is the link to the latest version of that skin on KVR:

I double-checked and there is nowhere to uninstall Z3ta+, has anyone else run into this and how did you get around it to update it?
Here is what the Support section of the site says to do, I could manually delete the files, that part's easy but it says to first go to Add/Remove programs, but it isn't listed there.
 
Maybe these instructions mean EITHER use Add/Remove, OR manually delete, but it doesn't say that. I don't want to manually delete the files, and then the update won't work, I want to make sure it will work first. Certain programs are like that, where you have to use Add/Remove first, then to get rid of certain files left behind, you go in and manually delete those.
 

 Uninstall any previous versions of Z3TA+

Using the Control Panel 'Add/Remove Programs' option

Perform a file search for files named 'Z3TA+*.dll', and delete them manually (this includes both synth and effect versions).

Install Z3TA+ 1.5.3

Run the 'Z3TA+150Setup.exe' installer, and follow the installer instructions.

For new systems, there's no need to install any earlier version of Z3TA+ before installing 1.5.3. 

Sorry, been away.  I've got an uninstaller program in my Cakewalk/Z3ta+ folder.  See if there's one in yours and use it instead.  You might want to copy all your current files to an external drive before installing 1.5.3 just to be safe.
