Activities not visible (like "Write Line") even though System.Activities package is installed

Help Studio

Hello everyone,

I’m facing a very strange issue with a fresh installation of UiPath Studio Community. My goal is simply to create a new process and use basic activities like “Write Line”.

The Problem:
My Activities Panel does not show any core activities (like “Write Line” or “Message Box”), even after I confirmed that the UiPath.System.Activities package is installed and listed in my project dependencies.

Troubleshooting steps I have already taken:

Performed a full, clean reinstallation of UiPath Studio.

Diagnosed and resolved a firewall issue that was blocking the package manager from connecting to the internet. I have created a permanent "allow" rule for UiPath.Studio.exe.

With the firewall rule in place, I successfully searched for and installed the UiPath.System.Activities package.

I can confirm that UiPath.System.Activities is visible in the "Manage Packages" -> "Project Dependencies" list.

Even after the package was installed, the activities were not visible.

I tried forcing a package reload by changing the version number and saving.

I created a brand new, empty project to make sure the project file itself was not corrupt.

Despite all these steps, the activities from the installed package are still not visible in the Activities Panel.

Has anyone seen this behavior before? What else can I check? Are there specific log files I should look for?

Thank you for your help.

Hi @j_h2

Which package version you have installed?

Have you tried downgrading its version?

If you open any previously created project, does it show the activities?

Hi,

Thanks for getting back to me. Here are the answers to your questions:

  1. Initial Version: We started with package version v25.10.0.
  2. Downgrade: I have now downgraded the package to v25.8.1 to test it, but the issue still persists.
  3. Previous Projects: This is our first project, so we don’t have any older projects to check for comparison.

Since downgrading did not solve the problem, what would you suggest as the next step?

Thanks for your help.

Hi, quick update: I’ve solved it!

It was my mistake, I was simply in the “Project” tab instead of the “Activities” tab. :man_facepalming:

Thanks for your willingness to help, we can consider this issue closed.
