Recently I was working on a sandboxes solution, which included a WebTemplate (Vesa “Vesku” Juvonen wrote a really nice post about it), but I couldn’t deploy it, the followin error was displayed into Visual Studio 2010:
Error occurred in deployment step ‘Add Solution’: Exception from HRESULT: 0x8107026E
After checking the Logs (in %SHAREPOINT ROOT%\\LOGS) the following error was found:
Failed to open the file ‘Features\AD6.Public_AD6_Web\AD6PublishingSite\onet.xml’.
#2006e: The specified path “” does not exist.
