"seems like Generic Application is for software failover, so what is the good option for application software running HA"

Yes, Generic Application is for software failover that does not have its own failover capabilities built in.. That seemed to be what you were asking for in your original post. Not sure what you mean when you ask about 'application software running HA'. Do you mean the software you are running has its own built-in HA? In that case, there would be no need to put it into a failover cluster. You would simply follow the instructions of the software vendor for configuring the HA within their product.

" install the software under Generic Application after that how Win 10 accesses the apps? "

When you install the application to the cluster, you define a resource name and IP address to the cluster which will be referenced by the users accessing the application.

What is the application that you want access? Maybe you should be looking at something like Remote Desktop Services instead of failover clustering. Maybe if we knew a little more about what you are trying to accomplish, we could provide better guidance. When you are asking about 'Win 10 access' to the application, this sounds very much like a Remote Desktop Services solution.

The software does not come with build-in software.

Etc: Win 10 client can access use the server app that I create0 "C:\Program Files\iVMS-4200 Station\iVMS-4200\iVMS-4200 Client"

Okay, so your application does not have built-in HA. Then it makes sense that if you want to provide a form of HA, you can install the software as a Generic Application. From your previous post you show an image of the iVMS-4200 Application properties. In there you have specified the name, 'iVMS-4200 Application', and the command line to execute when that application name is used. When you assign a name to a Generic Cluster Application, it creates a DNS entry. So after you have created your generic application on your cluster, an end-user can execute the application by using the name. In your case this is the 'iVMS-4200 Application'. That way when you go to execute it, it will be looked up in the DNS and the IP address you associated with the generic application will be combined with the command line name of the generic application, and the program will be executed no matter which node of the cluster the application is currently assigned to.

Continuation of above comment due to limit of number of characters.

Note that there are limitations to this method. First and foremost is that this does not automatically make an application runnable by multiple users at the same time. If you want multiple users to run this program at the same time, you might be better off configuring the application under Remote Desktop Services which automatically configures separate workspaces for each instance which is run. That is not done by the cluster service for a generic application. If your iVMS-4200 application is written to be a multi-user application, then there should be no problem. But if it is an application that is written to run in a client environment with a single user at a time, then you might have issues with attempting to run it in a cluster. You need talk with the application developer to see if the application is supported to be run in a clustered environment with multiple users accessing it.

Hi TimCerling,

I have been trying to search for information on how to execute the application by using the CMD or powershell. I tried the command cd C:\Program Files\iVMS-4200 Station\iVMS-4200\iVMS-4200 Client\iVMS-4200.exe or cd iVMS-4200 Application so far no luck to get it done....

Yes, and I have seen that you have posted your query in other locations. I have responded a couple times in a couple other posts.
