If you are trying to install ROBOTILL on a Windows 7 computer and you are getting the '.NET Framework Blocking Issues' error or another message about the .NET Framework, follow the steps below: Run all outstanding Windows updates on your computer. Restart your computer and check that your computer is up to date - if not, repeat the first two steps. Once your computer is up to date you can run the ROBOTILL install again - the install should now finish without a problem. If you still have a problem, download the latest version of the .NET Framework directly from Microsoft's website and install directly. It is only on Windows 7 that you might get problems with the .NET Framework install as the .NET Framework is automatically installed on Windows 10.
