Uninstalling Visual Studio 2017 "Unexpected character encountered while parsing value" - visual-studio

I'm attempting to uninstall Visual Studio Enterprise 2017 using the Visual Studio Installer on Windows 10 Professional but when I try to do so I hit this error:

What might be causing this issue?
The error Visual studio gives me is:
Error 2 Web deployment task failed. ((1-10-2012 18:54:34) An error occurred when the request was processed on the remote computer.)
(1-10-2012 18:54:34) An error occurred when the request was processed on the remote computer.
The server experienced an issue processing the request. Contact the server administrator for more information. 0 0 Database
--FIX--
For some reason my installation of Webdeploy 3 did not work well (tried reinstalling too) with ms authentication, created a sql auth connectionstring and it resolved the issue.

WCF service attempting to read mdf file

I have a Silverlight application, developed in VS2010 and deployed on Server 2008.
The application calls a WCF service within the project to read an mdf file, again within the application.
After getting through a number of what can only be called bugs within the VS deployement system (missing out the svc.cs file, placing the references in a folder the service can't see) I have managed to get it running.
The problem I'm having is that the service fails after a few seconds. Using WCF Storm I was able to run the service and get the following error information:
removed, see comments and below
has anyone any suggestions as to how to fix this? I'm getting to the end of my tether with WCF services!
Thanks in advance

It looks like the service cannot see the database. I'm not particularly experienced with this sort of thing so I may be missing something important.
Within VS2010 I have the mdf file inside App_Data within the webpage. The service is within the services folder. I have published the site and moved the files and folders to a new folder within wwwroot. Any ideas?
Thanks again

Your problem is one of these:
your connection string is wrong:you must open web.config file in your web part of your project and right that.
database system is inaccessible because:
the database computer is turn off
firewall or antivirus of database system is active
