I have a Windows 8.1 machine that needs to edit workflows within SharePoint Designer (2013 SP1).

Whenever a workflow is clicked on one of two errors is received:

  1. Server side activities have been updated. You need to restart SharePoint Designer to use the updated version of activities.

  2. Windows Workflow Foundation, part of .Net Framework 3.0 must be installed to use this feature.

    Screenshot of Microsoft SharePoint Designer error message "Windows Workflow Foundation, part of .Net Framework 3.0, must be installed to use this feature.

Restarting does nothing to correct the errors.

Several blogs or support sites have recommended deleting temporary files which hasn't helped. I have reinstalled SharePoint Designer as well.

Another Windows 7 machine is also having the same issue with the same site.

It seems to be an issue with the site. The site is hosted on SharePoint Online.

  • Just wondering if you ever managed to fix this. One of our Windows 7 workstations has been suffering from the same issue for months, but I never managed to crack it. (Most likely eventually going to do a clean install of Windows) Jan 18, 2015 at 12:19
  • No, we stuck with using the workstations that didn't have the issue :(

  • I'm trying to solve this issue for 3 months now, for no avail. I usually stumble upon @praveen suggested solution. But it just doesn't work. Aug 17, 2017 at 18:57

I followed directions on this website and was able to open my workflows again.

Basically, I cleared the following caches and restarted SPDesigner:

%APPDATA%\Microsoft\Web Server Extensions\Cache

%APPDATA%\Microsoft\SharePoint Designer\ProxyAssemblyCache


I also installed the Microsoft SharePoint Designer 2013 (KB3114721) update.

  • Just installing the update fixed it for me 🤙 Much headache avoided 🙌

Installing the update above, ensuring that .NET Framework 3.0 was installed and then clearing the cache worked for me.

#Add Module Install-Module -Name DotNetVersionLister -Scope CurrentUser #-Force

#Check to see which/if .NET is installed and what version Get-STDotNetVersion


I've got this error unexpectedly after years of using SP designer on particular host with particular workflow-enabled library. I've tried all the solutions from this topic with my Windows10 but only my own worked. Kind of shamanic magic:

  1. Open another (sandbox) subsite of target site collection in designer.
  2. Create 2013 simple list workflow on any library. Publish it.
  3. Re-open target site in designer and workflow to edit. It shoud work. Test WF from step 2 can be deleted.

For me, installing the .Net Framework 3.0 sp1 (not 3.5 or any 4.x) fixed it. https://www.enjoysharepoint.com/windows-workflow-foundation-part-of-net-framework-3-0-must-be-installed-to-use-this-feature/


Installing this update from Microsoft and then restarting fixed it for me. Download SharePoint Update


Yes, that did fix it for me. Thanks
