Hello Kingrives,
As correctly mentioned by Bernd that the standalone Adobe Reader is not available which requires no installation. You may have to contact your IT team to get Adobe Reader installed, or have to ask them to provide full admin rights to download and install Adobe Reader.
You may share the installation link with your IT team so that they can download and install Adobe Reader Adobe - Adobe Acrobat Reader DC Distribution
Feel free to update this discussion for any further assistance.
Thanks,
Anand Sri.
