The questions I'm trying to answer are whether it is possible to patch existing Reader DC client installations (not the AIP itself) without uninstalling and reinstalling (our current practice) and what specific command to use to send the update.
Executing the command below I get "The upgrade patch cannot be installed by the Windows Installer service..." error.
msiexec.exe /i "xyz\acroread.msi" /update "xyz\AcroRdr2017Upd1701130105_MUI.msp"
Is it possible to just install the .msp file without calling the original .msi? If so what is the command for that?
For reference our AIP process is like this: (from another post but describes it well)
1. Create an AIP for the base version of Acrobat by using the following commands (Base Release):
msiexec /a <xyz\AcroPro.msi or AcroStan.msi> TARGETDIR=<different path to folder where the AIP must be created>
2. Apply Patch (MSP) using below command (you will get the msp from the extracted folder <xyz>:
msiexec /a <path to AcroPro.msi/AcroStan.msi in the location where the AIP was created at step 1 in TARGETDIR> /p <path to msp patch>
You will get a patched AIP.
3. Install the AIP created by using the following command:
msiexec /i <path to AcroPro.msi/AcroStan.msi in the location where the patched AIP was created>

The simple command line to install patch is
msiexec.exe /p "C:\MyPatch.msp"
remember that all patches have a target, which is usually full base product (not deployed from patched AIP)
For example, if you want to patch Adobe Reader DC, the base version is here
ftp://ftp.adobe.com/pub/adobe/reader/win/AcrobatDC/1500720033/
Pay attention to MUI versus single language installer; they have different patches.
Maybe this topic will be helpful as well-

So you're saying that there's no method to patch installs deployed from a patched AIP?
