Thanks, Bandeep. That seems to have solved that issue, but now when I try to 
load AE I get an error message popup that states: 
"org.apache.uima.resource.ResourceInitializationException". I'm not sure what 
this means? It only happens when I try to load the AEs that utilize UMLS.

Thanks in advance.

Hi Milena,

It looks like a classic example of Java version mismatch. One of the 
dependencies of cTakes is Java 8
Please make sure you have JAVA SDK installed and not JRE. I have OpenJDK 8 
running on my system and cTakes runs fine on my system.

I have just installed cTakes and followed instructions in the 3.2 User Install

Guide, yet I get this error when trying to load any AE (even the non-UMLS ones):

 I have double checked that I have the latest Java software. Any idea what 
could be causing this error?

Thank you!
