Question: I have Visual Studio Ultimate 2012 that is working fine except for one issue. Whenever I try to connect through the sign in Wizard to Team Foundation Server I get an error in a popup Titled: "Script Error" as if it can't render the result or something. here are more info on the subject

```
Line: 4
Char: 16405
Error: Object doesn't support this property or method
code: 0
URL: https://....../TFS/Loader.min.js

```

Any suggestions? (I tried re-installing but the same issue shows)

Answer: 
As I'm using Windows Server 2008, I couldn't find a way to reinstall IE (only to enable/disable it), so [this](https://stackoverflow.com/a/28187268/578319) solution didn't work for me. But there is other workaround I found. When you try to connect to tfs server and the browser window "Sign in to TFS" inside Visual Studio opens with javascript error and then nothing happens, right click on the window and select "Properties" find Addres (URL) and copy full path (<https://app.vssps.visualstudio.com/_signin?realm=..>.). Paste this to Internet Expolorer (doesn't work with other browsers) and sign in to tfs and you'll be redirected to some tfs web service. After this switch back to Visual Studio and try to connect to tfs again. This time you should connect without need to log in.
Update of IE is not an option for me. I need it for testing on this machine. In my case following helped me:

I opened developer tools of IE8 (press F12). It was in 'IE8 Compat View' mode. I switched to 'IE8' mode and specified Document mode to 'IE8 Standards'.

Then I were able to sign in to TFS through IE8. Once I signed in using browser I restarted Visual Studio and everything worked correctly.
