Adobe Acrobat XI,some colors don't show up when they are highlighted (for example yellow does not appear)

[Spaul531]

When I highlight words myself or open up documents that are supposed to be highlighted (from people who sent them to me) sometimes the highlighting is missing. What do I do?

Hi Spaul531,

There could be a possibility that the application has some pending updates to install.

• You may first check the pending updates, launch application>Help>Check for update
• If that doesn't help, Go to >Help> Repair installation.

Let us know if it doesn't help to fix this problem.

Hi,

I tried doing the 2 things you suggested but after restarting my computer I am having the same issue.

Hi Spaul,

What is the exact version of Adobe Acrobat you are working on? Launch Acrobat>Help>About Acrobat.

Hi, it is Adobe Acrobat IX.

Acrobat IX is a very old version of Acrobat series, which has also now been declared as a discontinued product. 

There could or could not be a possibility that it has the compatibility issue with the operating system you are working on (if you have the latest one).

End of support | Reader 9 and Acrobat 9 (and earlier)
