Rational Performance Tester (RPT) Installation

 Good morning,

Forgive me in advance if this is not the right place to ask, but I've tried multiple support desks and have had no luck on solving this issue.

I am trying to install the latest version of RPT (10.0.2., from 8.3.) The installation instructions stated that I should uninstall the previous version before moving to later versions, so I uninstalled using IBM Installation Manager. Then I downloaded the rpt10021.update.disk1.zip file from Fix Central and extracted it. In the IBM Installation Manager, under File, Preferences..., -> Add Repository..., when I point to either rpt10021.update.disk1/RPT/disk1/ad/repository.config or rpt10021.update.disk1/RPT/disk1/md/repository.config, I get an error stating "Repository rpt10021.update.disk1/RPT/disk1/ad/ (or md) can not be opened directly. It must be opened through disk 1 at rpt10021.update.disk1/RPT/disk1."

Your time and help is appreciated. Thanks.
