There appears to be no problem. I have no idea, sorry.
Thanks for using our products.
First, please make sure you have Adobe Creative Cloud installed.
Next, please check if the following exe is present.
C:\Program Files\Common FIles\Adobe\Adobe Desktop Common\RemoteComponents\UPI\UnifiedPluginInstallerAgent\UnifiedPluginInstallerAgent.exe
If they are not present, please install Adobe Creative Cloud.
Best regards.
