When should I use High-Density Robots?

In which situation do I have to switch to “High-Density Robots”?

As I know on a windows server there could be 2 persons connected on same time. For me it makes sens to start with “High-Density Robots” in the case more than 2 Robots are running on the same time?

(The bad thing about enabling the “Remote Desktop Session Host” feature is the additional costs for windows server)


Please refer the below link, it clearly explains about High-Density Robots.

Yes you can use Orchestrator by going to the link : https://platform.uipath.com

and follow the process in this link: Managing tenants

If by learning you mean learning the Orchestrator installation process (infrastructure), I will need to request a trial of the Enterprise Edition (Left option after accessing the link bellow)



Yes Orchestrator installation process, This information helps. Thank you…
Let me try that

I downloaded Enterprise edition trial version and tried to install UiPath Orchestrator. After following all steps when i load URL getting below error. Please let me know if any fix can be applied.

HTTP Error 500.21 - Internal Server Error

Handler “ExtensionlessUrlHandler-Integrated-4.0” has a bad module “ManagedPipelineHandler” in its module list

Most likely causes:

  • Managed handler is used; however, ASP.NET is not installed or is not installed completely.
  • There is a typographical error in the configuration for the handler module list.
  • During application initialization, either the application initialization feature has set skipManagedModules to true, or a rewrite rule is setting a URL that maps to a managed handler and is also setting SKIP_MANAGED_MODULES=1.

Things you can try:

  • Install ASP.NET if you are using managed handler.
  • Ensure that the handler module’s name is specified correctly. Module names are case-sensitive and use the format modules=“StaticFileModule,DefaultDocumentModule,DirectoryListingModule”.
  • Ensure that any application initialization rewrite rules set SKIP_MANAGED_MODULE=0 when setting a URL that maps to a managed handler (such as .aspx, for example.)
  • As an alternative, ensure that application initialization rewrite rules map the request to an unmanaged handler (for example, to an .htm file, which is mapped to the StaticFileHandler.)

All prerequisites have been taken care but still getting below error.
