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.
