Take note of the remark on the installation instructions page from Juniper which states
For a Windows installation (.msi) that uses an automated distribution mechanism and where the users do not have administrator privileges, you should ensure that the installation is run in the proper context, typically the USER context. To install in USER context, first advertise the .msi while in the SYSTEM context. For example, to advertise the 64-bit Windows installation to all users, use the following msiexec command:
msiexec /jm \JunosPulse.x64.msi
