I'm unable to open and edit SharePoint workflows in SharePoint Designer 2013. However, when I uninstalled Visual Studio 2015 Enterprise from the machine, I was able to open and edit workflows just fine. Has anyone else experienced this and knows of a possible solution so that I can have both programs on my machine?

  • I am having Visual Studio 2015 Community Edition and SharePoint Designer run parallel. May I know the issue you are having when you try to edit the workflow? Jun 9 '17 at 15:50
  • When I try to open or edit a workflow I get the following: "Windows Workflow Foundation, part of .Net Framework 3.0, must be installed to use this feature." Or sometimes it asks me to close and reopen Designer. Jun 9 '17 at 16:14

As you described in the comment the error you might be getting because of cache issue.

You have to remove these cache files from 3 locations on your machine

%APPDATA%\Microsoft\Web Server Extensions\Cache

%APPDATA%\Microsoft\SharePoint Designer\ProxyAssemblyCache


You can refer the below post for additional reference



You need to install Office Tools for Visual Studio 2015.
