This page documents all system requirements and installation steps needed to prepare a development environment for building custom Workflow Analyzer rules for UiPath Studio.

It serves as the foundation for all subsequent learning artifacts in the HelloWorld Rule Authoring milestone.

Download the installers from the official sites, as linked above.

• Needed only for legacy rule targeting scenarios. If you are planning to use Workflow Analyzer to analyze even a single "legacy" project, then you need this.
• Run the installer with Administrator privileges. The individual images of this sequence can be found here. Use the browser's back button to return to this page.

• Download from: https://dotnet.microsoft.com/en-us/download/dotnet
• Run the installer for the .NET 6.0 SDK with Administrator privileges. The individual images of this sequence can be found here. Use the browser's back button to return to this page.
• Run the installer for the .NET 8.0 SDK with Administrator privileges. The individual images of this sequence can be found here. Use the browser's back button to return to this page.

• It is assumed that you already have UiPath Studio installed.

After installation, confirm your setup with the following steps:

dotnet --version

Expected result:

• The command should print a version number, e.g. 9.0.x, but more importantly, it should exit without errors.
• No need to compare the versions shown in the output; just verify that the command runs successfully.

dotnet --list-sdks

Expected output includes:

6.0.x [C:\Program Files\dotnet\sdk]
8.0.x [C:\Program Files\dotnet\sdk]

To confirm .NET Framework 4.6.1 is installed:

1. Open Settings Press Windows + I.

2. Navigate to Installed Apps

   • Go to Apps → Installed apps.

3. Search for ".NET Framework"

   • Type .NET Framework in the search bar.
   • Look for:
     • Microsoft .NET Framework 4.6.1 SDK
     • Microsoft .NET Framework 4.6.1 Targeting Pack
     • (Optional) Targeting Pack (ENU)

📸 Example:

To confirm Visual Studio is working:

1. Launch Visual Studio Use the Start Menu or desktop shortcut.

2. Open a Solution

   • Go to File → Open → Project/Solution.
   • Select any .sln file.

3. Check for Errors

   • Ensure there are no missing SDK/component warnings.

To confirm required environment variables are available:

1. Check DOTNET_ROOT

   • This should point to the base directory where .NET SDKs are installed.

2. Inspect %ProgramFiles%\dotnet

   • This directory should contain one or more installed SDK folders.

3. Locate the active .NET CLI

   • Run the following command in your terminal:

     where dotnet

   • This will show the path your system uses to invoke the .NET CLI.

• Visual Studio Downloads
• .NET SDK Downloads
• UiPath System Requirements

Once your environment is set up and verified, you can proceed to:

• Fork and open the HelloWorld rule template project
• Learn how to build, pack, and deploy your first rule
