Can't upgrade Acrobat Professional 9.0 to Acrobat Professional 9.3

Question

We have been installing Acrobat Pro 9.0 on machines.  Now that the 9.3 update has been released we want to update the computers.  I have followed the instructions to create an AIP. 9.0, 9.1, 9.1.2, 9.2, 9.3.  When I attempt to install Acrobat Professional 9.3 on a computer that has Acrobat Professional 9.0 on it I receive the following error message.
Another version of this product is already installed.  Installation of this version cannot continue.  To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.
If I install the package I created on a computer that does not have Adobe Acrobat Pro installed on it, there are no problems.  The package is installed and it is at the correct version.
I obviously don't think I should have to manually remove Acrobat Pro 9 from the computers.  Shouldn't the patched 9.3 product install over 9.0?

Answer 1

Browse in the registry to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
Highlight {AC76BA86-1033-0000-7760-000000000004} or {AC76BA… as Adobe stuff usually starts with that
On the right you will see stuff like
DisplayName = Adobe Acrobat…
DisplayVersion = 9.3.2
This confirms the product and version.  So in the above example if you want to uninstall it this would be the command
Msiexec.exe /x{AC76BA86-1033-0000-7760-000000000004}  and then /qb or /qb! For no cancel button etcetera
So once I found my 9.0.0.332 SID I opened Adobe Customization Wizard 9, opened my MSI with attached MST.  Clicked on the last option in the left column, “Direct Editor”, then on the table “Upgrade”.  I looked in the list for my SID and saw several close ones but not the same SID.  So I made note of the VersionMin, Attributes, and ActionProperty of the similar row.  I then added a new row with the known SID I wanted removed and with the noted info from the other row.
Clicked save, which updated my mst.  I’m using a command that launches setup.exe.  I find that the settings in the transform are more consistent than when running a full msiexec i/…transform=…command.
When I run the setup.exe I see the msiexec window startup saying configuring 9.3.2 and then it flash to an msiexec window saying removing older version of the product followed shortly by installing 9.3.2
Done
