Fix Designer error: Server-side activities have been updated. You need to restart SharePoint Designer to use the updated version of activities.
When I tried to create 2013 workflows using SharePoint designer I got this error.
For some reason, I guess designer failed to download required DLLs into Cache folder. I tried different solutions suggested in various blogs but nothing worked for me except below approach.
Copy following files manually to the locations mentioned below.
Microsoft.SharePoint.WorkflowServices.Activities.Proxy.dll
Microsoft.Web.Design.Client.dll
for SharePoint Online, you have to copy these files at below location.
%USERPROFILE%\AppData\Local\Microsoft\WebsiteCache\Clients\<VersionNumber>
for SharePoint On-premise, you have to copy these files at below location.
%USERPROFILE%\AppData\Local\Microsoft\WebsiteCache\<SiteName>\<VersionNumber>
I am not sure whether it is a right approach or not. Because in future if Microsoft releases new version of above DLLs, we may have to copy latest files again.

ReplyDeleteFrom time to time, I meet the issues using SharePoint Designer. Usually I can reinstall the app or manually copy the missing files and up and running the SPD.
ReplyDeleteHowever, this time I can't even find the Dlls on any of my system!
This is much better site than any of Microsoft sites regarding to this issues! Thank you Gowri!
Microsoft is becoming junk application manufactory now.
