I'm back to play FreeSO today, so I installed all the requirements (FreeSO, TSO, .NET Framework), but not OpenAL.
Thanks to Norton 360's random malicious blockage, I'm unable to installing OpenAL on my PC.
Does anyone have the same problem like the topic I'm asking to you sims?
I do have Norton 360. I don't remember having that issue, but if you do trust FreeSO, yo can manually allow the installer to complete by clicking on the "Aficcher les détails" button on the notification you've got while installing it.
Once you allow it, I believe it should let you continue
