Hi Stafcy,
August 2014 and July 2014 CU more than 4 years old.
They are unsupported since around a year now.
Why should we Keep unsupported fixes up on our download center?
All fixes older than April 2017 CU are currently unsupported.
Starting April 10th, 2019 all fixes older than April 2018 CU will be unsupported.
Your customer should install a current CU patch level rather than trying to install an aged unsupported patch.
Cheers,
Stefan
