This error is generated because the default set of configuration values in web.config require IIS to treat the web site as an application but this has not been configured.

Solution:
1.Control Panel > Administrative Tools >IIS
2. Open webiste properties (Default Web Site>Your Website >Right click > Properties)
3. If the "application name" (under "Application Settings" on the "Directory" tab) is greyed out then click '[Create]' and then '[OK]'.

Error: Path for project must have only one segment

Even Though google shows 995,000 pages containg the text “Path for project must have only one segment” – None of them really explains what this error mean – Except if you look at the source code of WorkspaceRoot class, particularly ‘getProject’ method:

This problem usually occurs when you try to access a project name/path,etc, when it is not avialable or you might have forget to instantiate the IProject object or try to instantiate the IProject with different name.

Solution: Have a look at your code where you are calling

getProject. 

Check names, paths are called correctly.
