Error "No reference to the project is known"

Question

After having updated Studio 2015 (SR2) I get the above message. 
 I get the message: "No reference to the project is known", when I try to open a project in Studio. If I continue, Multiterm is not working - it says that the system cannot connect to my Multiterm file. When closing the Studio and starting it again, Studio and MT seem to be working again. 
 I have tried to repair Studio 2015 without any luck. This appears on both my computers which are running with two different virus programmes. Windows Defender on my stationary comp. and on my laptop I have AVG. 
 The operating system on both computers is Windows 10 which is updated. 
 Hope I can get help here :-)

Hi Mette, 
 
It sounds as though you have a corrupted entry in your projects file. Can you rename your projects.xml file to projects.xml_old or something similar. Then restart Studio. You can find this file here: 
 
c:\Users\[USERNAME]\Documents\Studio 2015\Projects\projects.xml 
 
You will lose the list of projects in Studio, but not the projects themselves. Now add them back in again one at a time by using the Open Project command (Ctrl+O) in Studio and browse to the location of your projects to select the sdlproj file for each one. 
 
This may resolve the problem.

Hi both, 
 
Perhaps just try one more thing and then you should log a support case to get help with the installation. Uninstall Studio and then install again as admin. So select the installer in your file manager, then right-click and install as admin. Perhaps the cause of the problem is related to permissions and Studio has not been installed with sufficient rights to run correctly. 
 
But if that doesn't help please log a case. For licensing or installation issues that prevent you from working we have a route for all customers to get help. This can be achieved really quickly using this link:

Just fill in the form and submit it. If you can, use the Chrome browser to log the case, you'll get more success in completing the form, and make sure your email address is entered correctly or nobody will be able to get back in touch with you.

Thanks both. I do agree with you that it is frustrating, but worth noting that if a lack of admin rights is the issue then if you don't reinstall the problem will not go away. A reinstall isn't too much of a problem, it's something our Beta testers do in a production environment quite regularly. No need to return licenses or back up files anywhere... just uninstall and reinstall (as admin). Doesn't take too long. 
 
But I do understand your concern... so keep the details for support and if you do need some help please log the case and refer to this thread.
