Unspecified error (Exception from HRESULT: 0x80004005(E_FAIL)) (Web Service)

Question

I get the following error when I try to make a new Web Service Application (using ASP.NET)

I only get it when I try to make a Web Service.

I tried removing IIS Express and installing it again. I tried starting devenv.exe with /SafeMode and /ResetSettings but to no avail. I get the same error every time.

I am using VS2013 Premium and Windows 7 x64. Anyone got any other solutions?

Answer 1

Open your Visual stdio "RUN as Administrator". Any visual stdio 2013 2015 2017 will not throw this error if run as administrator.

Answer 2

Please try to do the following steps:

-Inside the IIS Manager administration tool, right-click on virtual directory "ControllerHelp" and choose "Manage Virtual Directory - Advanced Settings"

-Inside the section 'Physical Path Credentials' modify the user/password to the correct values, or choose the default ("Application user (pass-through authentication)").

if it is not working, please try to repair the installed version of visual studio
