Hi,

In general, UiPath doesn’t support forward compatibility. Especially 2018.2 or lower is different architecture regarding activities package etc with 2018.3 or higher. So it might be difficult to open them.

Regards,

As Yoichi mentioned the forward compatibility is not supported in UiPath

only way is to open the project in the latest version of UiPath Studio and try downgrading the activities, that will disable few activities and you’ll have to work on it again by adding the activities.

Downgrade to the version which can be supported in v2018 Studio

Considering you are trying to access on v2018, most of the activities will have to ve worked on if you open on the newer version and downgrade but you can give a try.

Always take a backup in performing any such operation.

Also, Upgrading the v2018 should be the recommended step too.
