Studio 2023.10.3 update can't run processes from Orchestrator

[MarekBruna]

We’ve updated our Studio Version from 2022.10.3 to 2023.10.3 which caused a following popup to come up when opening a Windows version project:

After confirming it the process runs fine from Studio but does not when triggered from the Orchestrator.
Can someone explain:

1. Why does every Windows project require such a reference import in the latest Studio version?
2. Do we need to update something on the machine where bot run to make the process work from Orchestrator?

The error message that shows in the Orchestrator or if you try to run a process from Studio without importing the references first is this one:

Hi @MarekBruna

Please check the below thread

'Then' and 'Else' position inverted in IF activity

Hi @Gwen When using the 22.10.4 version it’s better to upgrade all the packages to the latest version and keep the runtime rule as Lowest Applicable Version. So, that it will take the packages compatible with that version. [image] Regards

I’m not sure if these two issues are related, I font seem to have a problem with the if activities.

Hi @MarekBruna

Please update all the packages to the higher version and keep the runtime rule as Lowest Applicable Version and it will sort the issue.

Hi @MarekBruna

I have faced the similar error and when I updated all packages to the latest versions by keeping the runtime rule as Lowest as applicable the issue resolved.
