The error you are getting is coming when you are removing the mailbox role.
Therefore you are sure that you selecting the correct option? Do you have other CAS role holders in the Exchange org?

The screenshot you have posted is for adding a role, not removing the role.
You need to run Exchange 2013 setup from Programs and Features, selecting the option to change.

"i do have a iso of exchange 2013 cu5"

Where did you get that from, as they don't exist as far as I am aware.
Exchange 2013 ISOs are RTM and I believe SP1 only. All CU updates are the extracted file download method.

You need to put the installation files in the same place that they were originally.

It needs to be in the exact same location as it was when originally installed.
You need to double click on the CU5 download file and extract the file to a path.

You can get the location out of the registry, but the exact key I don't know for CU5.
It will be under this path somewhere:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
