The two-time Olympic singles champion confirmed on Tuesday the Games, where he will play in the doubles with Dan Evans, will be his final event.
Murray, 37, said recent injuries, which prevented him playing singles in his Wimbledon farewell earlier this month, mean he is now content with ending his career.
“I didn’t feel that way a few months ago when I thought that this is when I was going to stop,” said the Scot in his first interview since the announcement.
Murray, who has been hampered by a series of injuries in recent years, said in February he did not plan to play beyond the summer, but did not give an indication of when his final tournament would be.
An ankle injury in March and a back issue which required surgery in June put emotional farewells at Wimbledon and the Olympics – titles he won twice in his glittering career – in jeopardy, but he was able to play doubles with his brother Jamie at Wimbledon, where they lost in the first round.
Murray said his back issue will likely prevent him from entering the singles in Paris – a decision which must be made before Thursday’s draw – but he and Evans are capable of doing “very well” in the doubles.
“Me and Dan made the commitment to each other, that is what we will prioritise,” he added.
“That gives the team and us the best opportunity to get a medal.
“My back is still not perfect. I didn’t feel great in the build-up to Wimbledon and during it. I feel better here”.
