Activities get lost when created with older UiStudio version?

Help
1

Hi there. I have problems opening some example zip´s when the root file was created with older versions of UiPath Studio. Main activities are not available. This happens out of zip´s from the forum and also throughout Level 1, 2 and 3 Training. In Level 1 there were the zip´s of Lesson 11 Practice 2 and Lesson 12 Practice 1 and 2 issued with this, on Level 2 and 3 there are parts of the GetCredential Catch Block of the REFramework not available. Deleting them and replace with other structure kept me going, but this should not be the straightforward way, not…?

Go to Manage Package and update the respective package whichever is throwing error. This will fix your problem without replace with other activities.
