I am facing the same issue
I tired to install all the packages when ever I login to the application and then again if I close and open the application… The same error is popping up
Can you find me some solution regarding this issue !
Should I check in to the auto update checkbox in manage packages window?

Thank you in Advance,




where is uipath installed, which is the version?

make sure the packages are being installed on the root folder.



I have installed uipath on my personal laptop with 2016 version
when ever I close and open the application I am facing the same issue and also I have been installing all the packages whenever I signed into the application!
so it is being a problem for me to drag the already designed xaml files and work on it
what exactly I should do now? am new to ui path so please guide me clearly about the root folder


I am still facing the same issue even after updating the packages, could any one please help me out.
