Symptoms:
When installing the Windows agent with a full UI on a device without Windows Installer 5.0, you will receive runtime error 2885.
Diagnosis:
Starting with the release of 2019 R2 (version 14.0) a hyperlink control was added to the installer dialogs to access our clickthrough EULA. Support for hyperlinks was added in Windows Installer 5.0 (Server 2008 R2/Windows 7 and later). If you install the agent with a full UI on a device without Windows Installer 5.0, you will receive runtime error 2885.
Solution:
If you are installing on a version of Windows that does not support Windows Installer 5.0, you will need to run the installer silently.
EXE: setup.exe /s /v"/qn"
MSI: msiexec /i "FlexNet Inventory Agent.msi" /qn
