None of the projects (including bundled examples) are visible in the DevTest Portal. Getting errors on the console: <Error id="401" message="Authorization failed"> </Error> 

All Devtest Components were started as executable and as Services.  basically, two processes for each component. 
for example: 
Portal.exe and PortalService.exe were running at the same time . This probably caused locks on the Project folder.   

All supported DevTest Environments

Stopped all the services .  Started DevTest components as Services  and not as executable.
