Applying 9.1.2 to existing admin install point

Adobe please fix your patch to properly detect your own product!

This is 100% an error in the 9.1.2 patch. As promised here are more details:

What works:

1. Fresh install of Adobe 9.1.0. > Install 9.1.1 .msp. > Install 9.1.2 .msp.  OR
2. Apply the 9.1.2 patch to the Adoble 9.1.0 installer, (msiexec /p <9.1.2.msp> /a <9.1.0.msi>) Fresh install.

What does NOT work:

50+ PCs on a corporate network were silently and remotely installed with Adobe Reader 9.1.0 minus Adobe Air with the 9.1.1 patch included. (msiexec /p <9.1.1.msp> /a <9.1.0.msi>) The updated .msi was then customized with the Adobe Customization Wizard 9 to silently accept the EULA, silently install, etc. Some of the steps in the process were followed from here:  (but not all)

When you try to install the 9.1.2 patch to these systems, the following error message is displayed:

"The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program.  Verify that the program to be upgraded exists on yoru computer and that you have the correct upgrade patch."

So it's pretty simple: The product checking built into the 9.1.2 patch is simply NOT detecting the above mentioned 9.1.0 + 9.1.1 install. My guess is that the 9.1.2 patch is looking for a specific CLSID in the registry. And that CLSID is not written when reader 9.1.0 + 9.1.1 is installed via the above method.

You may want to check out the thread about updating to 8.current version. It seems like the patch on that one only works for an older version, not the newer versions. Could be the same is happening here.

I was having a similar problem. I was able to update the admin share (msiexec /a shared.msi /p AdbeRdrUpd912_all_incr.msp) I then told AD to redeploy the package. On restarting test workstations, it said it was installing. On starting Adobe Reader it said "configuring Adobe Reader 9.1.2," but in the about screen, it said it was version 9.1.0. I would get the same error if I tried to apply the patch to the updated but still 9.1.0 installs.

What seemed to work is if I added the 9.1.2 install as new software package, to be installed as an upgrade to 9.1.0, removing 9.1.0 before installing 9.1.2. I have not had any problems since.

What surprisingly did not work was installing the patch on a 9.1.0 workstation and then moving the files in the "setup files" folder to the admin share. The patch did not touch those files and that just reinstalled 9.1.0.

I initally had that problem.  What I ended up doing was creating a new admin install point with the 9.1.0 msi file.  I then patched that install point with the 9.1.2 and, voila, I had a patched version.  Now I just can't get it installed - it keeps telling me there is a current version installed....

Running into the same problem here.  AIP was created with 9.1.1; when I try to apply the 9.1.2 patch it fails with "The upgrade patch cannot be installed by the Windows Installer service because  the program to be upgraded may be missing, or the upgrade patch may update a  different version of the program. Verify that the program to be upgraded exists  on your computer and that you have the correct upgrade patch."  The error in the Windows Installer log is 1642.

Looks like the equivalent patch for Reader 8 has the same problem:

If anyone has a fix, I'd love to hear about it.

I am having this *exact* same problem at our company on over 50 PCs.

"I am trying to patch my existing admin install point of Adobe Reader 9.1.1 to 9.1.2 but get this error:

The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program.  Verify that the program to be upgraded exists on yoru computer and that you have the correct upgrade patch.

I get the same error on my PC when I double click the msp file"

I'll post more details shortly.
