Horizon view agent silent installation fails with below error: Silent installation fails because Windows requires human interaction to install driver not signed.
The VMware driver is digitally signed by Microsoft, however, we do have reported edge cases with the above error .
This error can happen due to certificate / permission issues on the VM. In this case, the installer is unable to find VMware certificate in the virtual machine's 'Trusted root cert authority' so treats the driver as 'Unsigned'.The problem may also occur if using a hardened OS image, please verify before hardening and use an inspection tool such as procmon to discover the particular conflict.Group Policy can be set to check this signature explicitly and block third party publisher certificates.
