Cleansing Package component is missing in DS 4.2 installation setup

Hi ,

I am installing DS 4.2 and I also want to install DQM cleansing packages 4.1.

As per the installation document In the installation window Cleansing Package component is there.
The PERSON_FIRM.zip file, located within the cleansing package .zip
file, must already be copied to the correct location. If the cleansing
package data is not found by the installation program in the expected
location, the option is disabled.

But i didn't find the component itself in the installation screen. How can i get the component . Please find the attached installation component screen for reference.

Thanks & Regards,
Ramana.
