This used to happen (very) occasionally where a restart would solve the issue, but now it is happening daily. Moreover, it's happening in different stages, e.g. create Excel instance, removing rows from a collection, deleting files etc. Any one familiar with this issue and how to solve it? Thanks, Jeroen &nbsp; Mon, 18 Mar 2019 11:13:00 GMT https://community.blueprism.com/t5/Product-Forum/Could-not-find-a-part-of-the-path-C-Users-username-AppData-Local/m-p/49693#M5051 JeroenOosterhol 2019-03-18T11:13:00Z https://community.blueprism.com/t5/Product-Forum/Could-not-find-a-part-of-the-path-C-Users-username-AppData-Local/m-p/49694#M5052 Has anyone else experienced this?
