"On behalf of Robin's family, we are asking for privacy during our time of profound grief. As he is remembered, it is our hope that the focus will not be on Robin's death but on the countless moments of joy and laughter he gave to millions."
Meanwhile, the last social media posting made by the 'Hook' star - who had long battled depression and checked into rehab last month as part of a sobriety maintenance programme - was a touching tribute to his daughter Zelda on her 25th birthday on July 31.
Sharing a sweet picture of his offspring as a child in his arms, he wrote: "#tbt and Happy Birthday to Ms. Zelda Rae Williams! Quarter of a century old today but always my baby girl. Happy Birthday @zeldawilliams Love you! (sic)"

Robin Williams still has four movies left to release.
The 'Patch Adams' star was found dead in an apparent suicide at his home in California yesterday (11.08.14) but fans will still be able to enjoy some new work for some time.
Over the Christmas period, he can be seen again as Teddy Roosevelt in 'Night of the Museum: Secret of the Tomb', which finished production in May and will be released on December 19.
A month earlier, there is another festive film being released.
He shot comedy 'Merry Friggin' Christmas' with Wendi McLendon-Covey, Lauren Graham and Oliver Platt and the Joe and Anthony Russo-directed picture will be in cinemas on November 7.
Additionally, the 'Aladdin' star lent his voice to animated pooch Dennis the Dog in live-action comedy 'Absolutely Anything', which also features Simon Pegg and Kate Beckinsale and will be released some time next year.
A fourth film, 'Boulevard', debuted at the Tribeca Film Festival earlier this year but has yet to find theatrical distribution.
And Robin had been meeting with screenwriter David Berenbaum about a sequel to his hit 1993 comedy 'Mrs. Doubtfire' - in which he played a man who masqueraded as an older female nanny in a bid to get close to his kids - with a second draft underway.
The project's director Christopher Columbus hailed Robin as a "genius" who he loved working with.
He said in a statement: "We have lost one of our most inspired and gifted comic minds, as well as one of this generation's greatest actors. To watch Robin work, was a magical and special privilege.
"His performances were unlike anything any of us had ever seen, they came from some spiritual and otherworldly place. He truly was one of the few people who deserved the title of 'genius.'
"We were friends for 21 years. Our children grew up together, he inspired us to spend our lives in San Francisco and I loved him like a brother. The world was a better place with Robin in it. And his beautiful legacy will live on forever."

Designer Judianna Makovsky says creating outfits for superhero movie stars like Scarlett Johansson represent her biggest challenge.
The award-winning designer has created outfits for 'The Hunger Games' and 'Harry Potter', but says that her recent work on 'Captain America: The Winter Soldier' - which features the 29-year-old actress - represented her toughest professional challenge.
Makovsky told Vogue: "Marvel has an incredible knowledge of the character, so we work with them throughout the process, but - although they have to be recognisable - the characters do inhabit different worlds in different films.
"There's a lot to balance. Superhero films are definitely the most labour-intensive for a costume designer."
Makovsky said she's found it especially tough designing a costume for The Black Widow, Scarlett Johansson's on-screen character in 'Captain America: The Winter Soldier'.
She explained: "Scarlett didn't actually start to fit for the catsuit until two days before we started shooting, so we had to do lots of trials and testing in quite a short timeframe. It was a challenge to get that many looks done in time.
"We work very closely with the actors on an action movie. We'll make different versions of the same costume depending on what she's doing: boots with running heels, fighting heels, standing heels; costumes that will allow her to kick; others that will accommodate a harness."
