  45. Thanks!!! I’ve been trying for a week to correct this!!!

  46. Months of hell trying to get this Outlook to work . This really works !

  47. Thanks a lot bro, this is the best solution for this issue so far =)

  48. Perfect. You are a genius.

  49. Thank you so much for the straight forward easy to follow fix, you “ROCK” as usual Microsoft website was a frustrating trail that led nowhere

  50. Your resolution surpasses all the other resolutions. The major question is what caused this to go from working to not working. I guess it’s one of the updates I took in the last week (IE 10 service pack, etc)

  51. Just perfect. I could not restore the access after removing the chrome (just hate the damn Adobe install it by default) using all different ways listed on the MS supporting site. But the trick listed here just worked like a charm. Thank you so much.

  52. WOW– it worked; thank you so much. Was also easier than all the other fixes which did NOT work. Copy Paste worked. Nice.

  53. Worked instantly when Microsoft’s own ‘Fix It’ couldn’t!
    Thank you so much!

  54. I had tried so many sites looking for advice (and tried all of them) but none worked. This worked immediately. Thank you!!

  55. Thanks so much!!! ๐Ÿ™‚

  56. After many problems with a torch.exe override on web and flv, this one fixed it.

  57. Absolutely works, fantastic. Thanks!

  58. when i open any application or any files that cannot be open.when i click file or application it say,”This operation has been cancelled due to restrictions in effect on this computer.”
    how to solve this problem.please help me.i am using windows 8

  59. Great fix! You don’t need to open the cmd window with elevated rights, in fact it should be run as the current user as the registry entries you are modifying are in HKCU.

  60. It’s work!! Thank you very much.

  61. Thank you so much! It works!

  62. Yay! this worked perfectly ๐Ÿ™‚ thanks

    So what to do? So, select and copy the 4 Reg-Lines. Close all taps. From START select in search COMMAND PROMPT and past the 4 Reg-lines in one go into it. And Bob is yr Uncle! Absolute a marvellous solution. THANKS AGAIN!!!! KEES.

  93. Ran into this issue on a clients laptop running Windows 10 with Outlook 2007.
    Making hyper links open by default in Chrome messed up registry.
    Followed all of MS technet articles:
    Tried following other registry fix’s but because Chrome wiped out settings was unable to.

    This little trick still works as of 11-2-16

    Awesome thank you for putting this out!
