Updating using the MSI the version is incorrect

I am trying to use the MSI to deploy Adobe Reader 15.020.20039.  Before running the MSI I am running version 15.017.20050.  I need to use the MSI so I can apply the transforms.  When I try to run the MSI its just trying to do a repair which isn't helpful so I am having to script the uninstall of Acrobat Reader before running the MSI.  My powershell code looks like this:

$Adobe = Get-WmiObject win32_product -Filter "Name LIKE '%Adobe%Reader%'"

if($Adobe){$Adobe.Uninstall()}

Start-Process -Filepath "msiexec.exe" -argumentlist '/i "AcroRead.msi" /qn TRANSFORMS=AcroRead.mst /l*v! c:\temp\AdobeReader.log' -Wait -Verbose

It installs and the transform file is applied but when I check the version its at 15.007.20033.  Also the GUID always stays the same.

Is anyone else running into this?
