BIG-IP VE Version 16.0.1 - VMware Workstation power-on script

I'm not sure why that's happening, but can confirm the behavior as well. You can get rid of the warning by changing these lines from true to false in the vm config file.

toolscripts.afterpoweron = "true"

toolscripts.afterresume = "true"

toolscripts.beforepoweroff = "true"

toolscripts.beforesuspend = "true"

In fusion (not workstation) you can get to the config file directly by right-clicking on the VM while holding down the option key and selecting Open Configure file in Editor in the menu. In workstation I think it's control instead of option. Should work the same.
