Re: Play button takes me back to the launcher

@vsilva73  You can switch between the 64- and 32-bit versions of Sims 4 in Origin.  Right-click on the Sims 4 icon, select Game Properties > Advanced Launch Options, and choose the version you want from the dropdown menu.  This option is only available in Windows; let me know if you're on a Mac.

Are you sure you need to run the 32-bit Legacy Edition though?  If not, you can run a dxdiag and attach it to a post; that will show whether you need the LE or not.  Please also let us know what issue you're currently having; there's a good chance it can be solved without your needing to run the LE.
