dears i use Enterprise 10.9.1 with ArcPro, i want to install ArcMap 1081 i don't want to use it with Enterprise, i just work some times with ArcMap instead of ArcPro. But it gives me the following error, so any way to use ArcMap with Enterprise 10.9.1?

You're trying to install Enterprise and Desktop on the same machine? Bad idea. Install Desktop on a desktop and Enterprise on a separate standalone machine.

I agree with @Brian_Wilson that you should install ArcGIS Desktop on a different machine, but if you need to have them on the same machine you will need to install Desktop 10.8.2 instead of 10.8.1

thanks @ReeseFacendini @Desktop 10.8.2 doesn't appears on my ESRI downloads page, where or who can i get it!

If you are only doing testing and you really don't have another machine available then you could probably install Enterprise in a virtual machine using VirtualBox. That would isolate it.

Make sure the machine can run VirtualBox and make sure you have a LOT of RAM installed. 32GB or more. Then again, you really need a boatload of RAM even if you are just running Enterprise and Desktop on the same machine.

Usually it's easier to set up a second machine.
