ViGEmBus Silent install switch not working?

[rodw-wilkins]

Describe the bug
Attempting to perform silent install does not appear to work.

To Reproduce
Steps to reproduce the behavior (example):

1. Launching .MSI with: ViGEmBusSetup_x64.msi /qn
2. Nothing happens (no prompts, error, etc. - app doesn't install)

Expected behavior
Expecting to have the app silently install but it doesn't.

Screenshots
N/A

System details (please complete the following information):

• OS: [e.g. Windows 10 20H2 64bit]
• Feeder software: [e.g. ViGEmBusSetup]
• Driver Version: [e.g. 1.17.333]

Additional context
Manually installing via .MSI seems to work, just quiet install doesn't.

Turns out it wouldn't install because it needed elevated privileges. I used this method from elevated command prompt and it installed silently.

msiexec /i ViGEmBusSetup_x64.msi /qn
