Hi,

I'm trying to open workflow editor window but it throws an error of "Application cannot be started. Contact the application vendor". I've tried to run the command "rundll32 dfshim CleanOnlineAppCache" and also tried to delete the files from "C:\Users\*YourUserFolder*\AppData\Local\Apps\2.0" but didn't succeed.

I've been using internet explorer.

After deleting the files and also running the command it only tries to connect but than disappear.

PLATFORM VERSION INFO
Windows : 10.0.17763.0 (Win32NT)
Common Language Runtime : 4.0.30319.42000
System.Deployment.dll : 4.7.3190.0 built by: NET472REL1LAST_C
clr.dll : 4.7.3324.0 built by: NET472REL1LAST_C
dfdll.dll : 4.7.3190.0 built by: NET472REL1LAST_C
dfshim.dll : 10.0.17763.1 (WinBuild.160101.0800)

Any solutions might be helpful.

Thanks.

You might need to change .NET Security prompting level in registry editor. More details in the link, but basically - set all values (except UntrustedSites) to 'Enabled' under Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Security\TrustManager\PromptingLevel
