Cause: The failed package cannot be found in any available sources in NuGet.config file from C:\Program Files\UiPath\Studio\NuGet.config (Studio/Robot installation folder).
Solution: As the KMParseXML seems to be a custom library, make sure that you added it firstly in the Local path or in the Orchestrator Host/Tenant libraries section or make sure that you are providing the correct source address in the NuGet.config file.
Example of NuGet.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<!-- Add this repository to the list of available repositories -->
<add key="Local" value="./Packages" />
<add key="MyGetOrg" value="https://www.myget.org/F/workflow/" />
<add key="MyGetV3" value="https://pkgs.dev.azure.com/uipath/Public.Feeds/_packaging/UiPath-Official/nuget/v3/index.json" />
<add key="Marketplace" value="https://gallery.uipath.com/api/v2" />
<add key="MarketplaceV3" value="https://gallery.uipath.com/api/v3/index.json" />
<add key="UiPath Packages" value="https://packages.uipath.com/activities" />
