SharePoint Exception 0x8107026E When Activating Module

When you encountered the 0x8107026e exception during the activation of the error, you should read the stack trace information to see if the error is related to the ONet.xml file. There would probably be a LocalizedXml function call which returned the error. This however does not provide the root of the problem. To find out what is going on, you need to open the SharePoint log files. These files can be found in a path similar to this:

%Program Files%\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS 

or if your system has the environment variable set properly, you can use this:

%SHAREPOINT ROOT%\\LOGS

Open the current file using notepad, so you can find more detail information on what is going on. This error is usually associated to the fact that the ONet.xml file is deployed to a different folder or just was not deployed. So if you look at the log, you can probably find this error:

Failed to open the file 'Features

and

The specified path "" does not exist

To resolve this problem, look into your project definition. First select the Web template folder and read the folder name under it. This is the expected folder name where the files should be deployed. Now make sure that this matches the name of the actual web template. Expand the folder and select the Element.xml file. Look for the Name property and make sure that this matches the folder name.

If the folder and template name are matching, you can now look to see how the ONet.xml file is being deployed. Select the ONet.xml file and look at its properties. The following properties should read as follows:

Build Action: Content
Deployment Type: ElementFile

Also look at the deployment location. This should match the folder name.Make the necessary changes and re-package your solution. This should address the error.

I hope this helps.
