Update application without admin rights?

I use this software at work, and due to company policies I can’t install this software without an IT administrator present. If I want to update the application I need to schedule a meeting with the IT department. Can this be done without admin rights?

The Listary service needs admin rights to be installed or updated.
How should that be avoided ?
Without the service, it’s not possible to index NTFS volumes.

The program everything which is very similar is able to have a portable version without admin rights. I hope listary can create a portable version which is able to do this.

I prefer the search commands of listary much better (ie search inside a folder, searching text in any order) and also jumping to folders while saving files much nicer. Same issue, work computer that I can’t install.
