The above instructions are a little confusing.

This worked for me:

1. Open Environment Variables window (Start menu, start typing "edit system" and "edit the system environment variables" should pop up as an option)

2. Click on Environment Variables button (bottom right)

3. Create a new System variable (Bottom "New" button)

4. Variable name should be: HOUDINI_DISABLE_OPENFX_DEFAULT_PATH

5. Variable value should be: 1

6. Hit OK

7. Houdini should now launch without OFX errors
