Hi naresh,

I think the Sales Campaigns plugin is not properly installed. Did you update the Core plugin as well when you added the Sales Campaigns plugin?
Please make sure you are using the same Core version as the Sales Campaign plugin.

Thanks

Yes did that, now getting this error

C:\Windows\SysWOW64\inetsrv> "C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe" /t:library /utf8output /R:"C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.Dy

I restarted the application, it worked, Thanks!
