Hi all, While I was working on SharePoint 2010 recently I came across some issues. I am putting them across so that anyone facing the same issue may find solution easily. Error: Error occurred in deployment step 'Activate Features': Feature with Id xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' is not installed in this farm, and cannot be added to this scope. Solutions: I was getting this error while ‘deploy’ing a feature from Visual Studio 2010. I searched the entire project for this GUID which is mentioned in the error. I did not find it anywhere. While troubleshooting, I opened the physical folder and opened ‘Feature1.feature’ file in notepad. This xml file was using the before mentioned GUID. I was not able to find it in VS 2010 :( I copied the GUID mentioned in the ‘Feature1.feature’ file and pasted it in the Feature ID section in ‘Feature1.Template.xml’ file. This solved the problem. Why I thought to mention it is because the exception thrown is confusing. It does not tell you...
