Cannot run Community-published project on Enterprise

[Craig1]

I have created a UiPath project using UiPath Studio Community Edition and published it to Orchestrator. This runs fine on the robot on the machine with Community Edition, but it does not run on a machine where a robot where the Windows Service version of UiRobot is installed, where it gives a ‘Error detecting project version’ error.

From reading this forum it seems the schema version can be changed in the project.json back to 3.2 from 4.0, but when I re-publish the project in Community edition it is immediately changed back to 4.0.

How can I run a UiPath project built on Community Edition on the Windows Service version of UiRobot?

Hi @Craig1,
Welcome to the Community!
Let mi remind about very important thing:

Editing project files is not officially supported

Hi, We would like to remind everyone that manually editing project files such as project.json or the .xaml files is NOT an officially supported way of solving issues. It can lead to unexpected behaviours of Studio when interacting with your project. We cannot provide any guarantees that your project will continue to work after ill-advised changes. Please be careful. Thanks!

We’re not supporting the run of the project made in newer Studio version on older version.
Sometimes operations on json file can help. But in cases like this I suggest to re-create project on older version.

In that case UiPath should be trying a lot harder not to have major breaking differences between Community and Enterprise versions of UiPath Studio.

But I’m not saying about difference between CE and EE. It’s the difference between package’s and app version. For example CE and EE (both in 19.4) will work identically. In your case you had difference between version numbers.

Hi @Craig1

Welcome to our UiPath Forum!

Please see my post here:

Getting "Error detecting project version" when project is run on machine with a minimal UiPath Robot installation

Hi @kwoxer Please see the article here first: We offer backward compatibility (you can run your older projects on new versions), but not forward compatibility (you cannot run newer projects on the older version because the older Robot does not understand the new features that were added in new version). In short though - Studio and Robot should be on the same version and the issue will never manifest itself. The easiest way to ensure you are good to go would be to install Studio from the En…

Getting "Error detecting project version" when project is run on machine with a minimal UiPath Robot installation

Well which version the current Enterprise version comes with? I think it’s Robot2019… isn’t it? Every installer will always come with the same version of Studio + Robot. Thus, Enterprise MSI installer 2019.4.4 comes with the robot 2019.4.4. I have re-read your original post to make sure we’re on the same page. Could you confirm if this scenario fits your case: You installed Studio+Robot using the community .exe installer on the machine that was used to create the project (this would be th…

I hope it gives sufficient explanation of how things work

The current versions available for download on your website are incompatible with each other. You don’t even give a way to download a version of Community Edition that is compatible with the current, older, version of Enterprise. And even if you did, Community Edition automatically updates itself to the newest version, so you’re back at the same problem again.
