I found the answer, I think, by reading through the documentation. The documentation, however, is outdated and shows one of uipath’s old installers, which allows you to select optional parts of the uipath ecosystem to install. The one that’s now available simply installs Studio and doesn’t offer these options.
The doc says to change some settings on the computer’s local group policy. That was helpful, actually. You have to give the Remote Desktop Users group access to three functions. It also mentions to run the installer as an administrator in order have the option of installing the local Orchestrator client that connects to the Orchestrator server. I had to then uninstall UIPath Studio, which was also tricky. I was not able to re-run the installer to modify or delete the install via “programs and features.” I was also unable to re-run the installer from the download link. It would crash after detecting my previous installation. I had to manually delete the UIPATH directory in my local profile, then re-run the installer as an Administrator. Finally, the Uipath icon appeared in my system tray!
I wish UIPath would include these important instructions at the beginning of the tutorial. I installed Studio at the beginning of level one, but didn’t find out the installation was missing the Orchestrator piece until about 180 tutorial slides later. When I went to the documentation, it referenced a .msi file that is no longer available. They must have folded everything into a single .exe installer. I lost several hours to this.
