Short of finding the GUID for every component and manually uninstalling them all, I'd just opt for running the old Receiver cleanup utility: https://support.citrix.com/article/CTX231094/citrix-receiver-desktop-cleanup-utility

Might want to uninstall using the product that was used to install it, obviously it was installed using the system account (see install source). Perhaps a simple PSEXEC -SID cmd.exe already does the trick, drop the uninstall string in there and it will run as system.

@Nick Panaccio old receiver cleanup utility didn't work

There's always Revo

que?

Try msiexec /x instead of I
