I am running Microsoft SP Designer v15.0.4551.1001 and I cannot open a workflow in the designer for a 365 SharePoint Online site. I get the following error -
Windows workflow foundation, part of .Net Framework 3.0, must be installed to use this feature
I have tried to clear the cache files at - %APPDATA%\Microsoft\Web Server Extensions\Cache %APPDATA%\Microsoft\SharePoint Designer\ProxyAssemblyCache %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache
Still no joy. Any tips advise how to resolve?
Any suggestions would be appreciated.
