Hi All, Iam getting the below issue when I try opening an already existing package which was working perfectly fine System.Xaml.XamlObjectWriterException: Cannot create unknown type ‘{http://schemas.microsoft.com/workflow/2012/07/xaml/activities}IsTrue’ I had UipathPlatform 2018.1.2 initially and In between I installed UiPath 2018.2 version where I had both these versions at the same time. Later I uninstalled both versions and re-installed the 2018.1.2. Now I get this error when I try running…

Hope this may helps you

Thanks
