+Known Issues
+============
+
+DLL file not found
+******************
+
+If you run your program in Visual Studio and encounter a "sycl.dll was not found" runtime error
+or a similar one such as the one shown below, update the project property :guilabel:`Debugging` > :guilabel:`Environment`. 
+To do this, follow `How to Fix`_ instructions.
+
+  .. image:: images/runtime_error.png
+    :alt: Unable to start a program: the code execution cannot proceed because XXX.dll was not found. 
+    :class: with-border
+
+.. attention::
+
+  The issue appears as the result of how Visual Studio 2017 and its later versions
+  handle additional directories for the ``PATH`` environment variable.
+
+How to Fix
+----------
+
+1. Open the project's properties, go to :guilabel:`Debugging` > :guilabel:`Environment` property, 
+   right-click the drop-down menu, and select :guilabel:`Edit`:

+
+2. Copy the default value of the ``PATH`` environment variable from the :guilabel:`Evaluated value`
+   section and then paste it to the section above it:

+
+3. Add to ``PATH`` the paths to the dll files that the program needs:
