Hi! 

Follow the output of WISM2 and CAP3700.

> Product Version.................................. 8.4.100.0
As already advised before, you should update to 8.5.182.7 as per link below.

8.4 has been end of support for more than 5 years and that release is deferred!

Yes Leo has the answer there. You should ignore the "gold *" version on software downloads - that doesn't get updated anymore and cannot be trusted (in other words 8.5.171.0 is broken) .  Refer to the TAC recommended link below for what versions to use.

In this case you should be using 8.5.182.7 - see link in my signature below.
