Win7 CC package refuses to install

I have been dealing with this issue for several days and can't seem to find an answer. We have purchased several seats for the Creative Cloud. We are attempting to create packages with the CC packager. Specfically, we created a package that contains InDesign, PhotoShop, and Illustrator for Win 7 64 bit. Neither the MSI nor the Setup.exe works.

The installation begins and the progress bar progresses to about 1/3 then stalls. It then shoots across and then rolls back quickly.

This is the 3rd time we've created this package.

I have tried to install this with elevated credentials and even under the local administrator account all with the same results.

I even contacted Adobe support and had the technician remote into my machine who then proceeded to screw up a whole host of settings - my bad I guess for trusting a 1st level technician. However, she did get it installed on my computer. I just have to go back and fix everything she broke. I am now trying to get this package (I created & downloaded a new version yesterday) installed on another computer and having the exact same trouble I had on my computer with the new package.

Both of these computers as well as the future systems have previous version of the same programs. In an effort to reduce possible issues regarding this, I uninstalled all previous version of InDesign, PhotoShop, and Illustrator. The only Adobe product that remained is an older version was Acrobat - 9 Pro.

These systems are connected to a domain and are runing ESET's endpoint antivirus. Yes, I disabled that and tried the installation again with the exact same results.

The latest PDApp.log has many Warings and a few Fatal lines in it.

There are quite a few: Failed to find Node  warnings.

Several: < GUID > is already installed

NOTE: I checked and recheckd, there are no instances of these applications installed even though it appears it thinks there are - registry issues?

Fatal errors:

5356 | Failed to remove the backup folder already present:5

5356 | Failed to create backup folder C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\\P7

5356 | package installation failed and the return code was -5

5356 | End Adobe Setup. Exit code: -5

4068 | The Bootstrapper Process is (-5).Stopping the installation process.

4068 | The return code from the Adobe Installer Process is (33).Stopping the uninstallation process.

...and the final line...

472 | utilLaunchApplicationDeelevated : The return Code from Create Process (1603)

Yes folks, the dreaded ambiguous Error Code 1603

So, anyone have any ideas as to why this installation will not work?

Let me know if you need more information.

I will be deeply grateful for any help.
