"Epifanía" is now compatible with Windows 10. This means that, theoretically, it is no longer necessary to download the RTPs on your computer to play it.

If for some reason it is still not compatible, try right-clicking on the executable and click on properties.

Then click on “compatibility” and select any operating system prior to Windows 10 (try Windows 98/me as your first choice).

If the compatibility problem persists, please let me know. Thank you very much.
