VMware Horizon 7.0 Agent install error 1921?
When you trying to create Master image for instant clone desktop Pool:
Error 1921.service VMware view composer guest agent server (vmware-viewcomposer-ga) could not be stopped .verify that you have sufficient privileges to stop system services.
Cause: This issue occurs if the view composer guest agent server service is not stopped by the uninstaller.
First cancel agent install process, Restart the guest OS and login as an administrator click start run type services.msc and click ok. Find view composer guest agent server service manually then stop & if you are not able to stop the service just disable the service and reboot guest OS. Log in as administrator then install VMware Horizon agent.
