Hi @huahe,
Welcome to the Community!
Could you give as some details about your computer? OS version and release. Which Studio version do you have and at which activity this error occurs?

Dear,

Thank you for your help!

OS version: Windows 7 SP1
UiPath Studio : 2020.10.2

This is not an error occurred in any activity, but occurred before the first activity was executed and after studio was started.

When I publish this process to robot, it works well.

It might be related to Windows 7 which is not supported OS anymore.
More details:

OK!Thank you!

Due to business system reasons, only Windows 7 can be used.
And under the new license mode, the robot needs to be upgraded.

We’re in a dilemma. :sob:
