Adobe Acrobat Reader DC Update Fails to install

[WISysadmin]

I have 5,000 PC's that are not able to install the Adobe Acrobat Reader DC Update 21.007.20099 PMPC-2021-10-12. When i try to manually execute the patch from CCMcache after extracting the .cab file it is asking for the CCMcache source for Acroread.msi. Any ideas how to resolve?

Hello

This is very typical for Adobe Reader and we see this a lot. A detailed analysis of the problem can be understood from this KB - it also contains guidance on how to resolve: https://patchmypc.com/system-error-1612-the-installation-source-for-this-product-is-not-available

This is documented as a known issue on Adobe's website: https://helpx.adobe.com/acrobat/kb/known-issues-acrobat-dc-reader.html

Ultimately this is a software vendor issue, or an issue on your devices causing C:\Windows\installer to be cleaned out (see article for more information). This is not caused or related to our catalogue or Publishing software.
