Question

I installed VS2012 from the web then joined a company that has a copy of VS2012 with the keys built in.. So I uninstalled the version from the web and installed the company version but I still get the “3 days left….”

So is there more uninstallation I must do somehow ? Perhaps some registry keys??

If your OS is Win 7:

• Clear your %temp% folder, they are all temp files. Ignore those files you cannot delete.
• We may need to reset templates. Open Windows Explorer, and navigate to \Common7\IDE (by default x86
  OS C:\Program Files \Microsoft Visual Studio 11.0\Common7\IDE
  x64 OS C:\Program Files(x86) \Microsoft Visual Studio 11.0\Common7\IDE
  );
• Delete the ItemTemplatesCache, ProjectTemplatesCache folder;
• Open Visual Studio Command Prompt (2012) under Start menu -> All Programs -> Microsoft Visual Studio 2012 -> Visual Studio Tools (run
  it with Administrator privilege: right-click the program -> Run as
  administrator);
• Run the devenv /InstallVSTemplates switch
• Run the devenv /Setup switch

If reset templates did no help, try reset Visual Studio

• Open Visual Studio Command Prompt (2012) under Start menu -> All Programs -> Microsoft Visual Studio 2012 -> Visual Studio Tools (run
  it with Administrator privilege: right-click the program -> Run as
  administrator);
• Try some devenv switches in command prompt:
  1. Run devenv /Resetsettings to eliminate the cause of corrupted settings.
  2. Run devenv /ResetSkipPkgs in Command Prompt.
  3. Run devenv /Safemode to see if you can apply it correctly. This can eliminate the possibility that third party Add-ins or
     packages are causing problems.
• Switch and try a new user account. This can rule out the possibility of corrupted user profile.

If you OS is Win 8, try to use All APPs page and open the prompt.

Also, you can try to run setup to repair Visual Studio.

If that doesn’t work I would suggest uninstalling and reinstalling.
