UiPath.Mail.Activities 1.15.2 installation fails

Hello, everyone,

We are currently using the following packages.

The studio version is 2021.10.4.


We would like to update package UiPath.mail.acitivites to version 1.15.2.

However, after installation via the Package Manager, we get the following messages:

What can be the cause here?

I can’t find the package UiPath.mail.acitivites 1.15.2 for a download outside of UiPath either.

Here the 1.12.3 can be loaded as the latest version. Why is that?

Many thanks in advance.

Hi @Prisemuetchen

In my environment i can able to install the Mail package version 1.15.2

Try to studio 22.4.4

Link to download studio : https://download.uipath.com/UiPathStudioCommunity.msi


Double-check to not have multiple Studio versions installed on your machine in Control Panel → Programs & Features. (Keep in mind that UiPath Platform is an old version of UiPath Studio)

After you installed Studio 2022.4.4, check the C:\Program Files\UiPath\Studio\NuGet.config to have something similar to this:

<?xml version="1.0" encoding="utf-8"?>
    <!-- Add this repository to the list of available repositories -->
    <add key="Local" value="C:\Program Files\UiPath\Studio\Packages\" />
    <!--  <add key="Local" value="C:\local feed path\" /> -->
    <add key="Marketplace" value="https://www.myget.org/F/workflow/api/v3/index.json" />
    <add key="Connect" value="https://gallery.uipath.com/api/v2" />
    <add key="Official" value="https://packages.uipath.com/activities" />
    <add key="nugetorg" value="https://api.nuget.org/v3/index.json" />
    <add key="signatureValidationMode" value="accept" />

Many Thanks. Is it mandatory to update the Studio version for the package update?

I don’t this so. Just have try to update the studio version @Prisemuetchen , It may resolve your issue

Hello @Prisemuetchen

Are you facing this issue only for the mail package updation or for other packages also?

It would be better if you try to update the studio and then update the packages.


Installing other packages works. We will update the studio version. Thanks.

Have you tried to reinstall the uipath studio and it working @Prisemuetchen
