Can anyone suggest some tools which they have used and had good results with process automation for a desktop application?.
We have a 3rd party application Onbase Studio. We add tasks, objects, scripts and also an external dll. We don’t have a lot of control over the application when it comes to deployment.
I am wondering if anyone has used process automation tools.

Sample basic use case is like this

1) Login/Connect to the application (onbase studio)
2) Click on the tab to upload and assembly. 
3) Navigate to the folder where the external assembly is located
4) Then click on upload and replace.

This is a simple flow

Another use case would be the following

1. Login or Connect to the application
2. Click on the tab to import a package file
3. Navigate to the folder with the package file and decision file
4. Import and add check points to make sure nothing extra gets imported.
   This is where it gets complicated.

Another use case would be to create a brand-new script when needed.

It is close to impossible to deploy these changes to a handful of customers every month manually.
