combine PDF Files option is missing from adobe Acrobat DC in the right click menu under windows 10

[Guest]

One of our computers is running the latest version of adobe acrobat and it used to be able to combine multiple PDF files in Explorer by selecting the files, right clicking, and clicking on “Combine supported files in Acrobat”. I am not exactly sure when this happened, but it no longer shows that option, I am probably guessing that adobe removed that feature in an update without telling us. But here is a list of things we have tried to fix the issue: 
1. removing and reinstalling adobe acrobat.
2. repairing the adobe acrobat installation
3. updating to the latest version of adobe acrobat from Acrobat X
4. doing the regsvr command to register the context menu in the command prompt
5. modifying the registry to make the context menu appear in windows
6. using the registry cleaner tool in CCleaner to fix any possible registry issues that could be causing the issue.
All of these listed solutions did not fix the problem, if anyone has any other possible solutions, please let me know. Thanks for your time!

I was looking for answers to this problem and for me, when selecting the files and right-clicking there is "Show more options". When I click that, the Combine Files in Acrobat tool shows up.
