The activation process of the InstallShield 2010 product using an AdminStudio 9.5 serial number requires a different set of files, and these files are not installed with the InstallShield 2010 prerequisite. This is a known issue in the AdminStudio 9.5 product.
A hot fix has been developed to fix this issue. Please follow the steps below to install the hot fix:
Download the attached public_hotfix.zip file.
Extract the files from the hotfix .zip file to the System subdirectory of the main InstallShield installation directory. (The default location of this directory is ?C:\Program Files\InstallShield\2010\System?)
Launch the InstallShield product and activate using your AdminStudio serial number.
Another option is to install the AdminStudio product, thereby installing the missing files.
This issue is being tracked internally by issue #IOA-000053331 and will be considered for a future release.
