After installing quicktime latest version in windows vista it didn’t start.It may give you an error message saying

Error 46: Could not find or load activex control

The Solution

There is an old NT utility called SubInAcl.exe that can be used to reset permissions in Windows XP and also in Vista.

Step 1: Download subinacl.msi from here and install it.

Step 2: Download modified version of reset.cmd from here and save the file in
C:\Program Files\Windows Resource Kits\Tools

Step 3: Open Command Prompt and type the following (hit Enter):

cd c:\program files\windows resource kits\tools

Step 4: Now type reset.cmd and hit Enter (You need to make sure you are logged in as administartor)

You will see the Command Line Tool running for some seconds. The issue should have been fixed and Quicktime should run again.

  4. Dude, I love you! I went through the whole thing you said in my Vista laptop SP2. Qtime was giving me that error 46 active x thing – it works now.
    Onlye one thing the command:
    cd c:\program files\windows resource kits\tools
    didn’t work, so used this:
    c:\program files\windows resource kits\tools\reset.cmd
    and that ran the script; I figured that “cd” meant change directory.
    How can I repay you?

  5. Thank you sooooooooooooo much !

  6. Worked perfect – you don’t even need to use the command line window though, I just went straight to reset.cmd and double clicked it, and it worked perfectly.

  7. Thanks! good info.

  8. just failed on my windows 7. have given up!

  9. hi, it does not work!
    I´ve tried everything as described, but it did not work.
    i have windows 7 64bit. i have installed subinacle.exe in program files (x86), i saved the reset.cmd in c:\program files (x86)\windows resource kits\tools; then i open the command prompt and i wrote c:\program files (x86)\windows resource kits\Tools; then i wrote reset.cmd, but when it finish and i open quicktime the error 46 still appears. Help me!

  10. Worked great thanks

  11. I don’t know what I’m doing wrong but I followed everything to the letter and still have a problem.I uninstalled and reinstalled, open as administrator and not, unchecked user account and rechecked, I’ve done evrything possible that I know of and still no luck. I get error message in the command prompt that reset is not a valid command. What is going on?

  12. In Windows 7 64 bits something changed and we can’t use subinacl to modify these keys anymore. I’m stuck with iTunes problems (no file associations on ipa and itms:// handling totally gone) and no Quick Time.

    Fuck Apple.

  13. hi,

    i use windows vista premium


  14. Fantastic! Thanks!

  15. Great fix works great now, my thanks to you IT guys out there you make the net the most powerful information resource created since printed text was invented :)

  16. Hi all Im running windows 7 Ultimate, and ran into the same problem, However after several attempts I went to the reset file which is allocated in the above instructions.
    This worked for me and not sure if it will work for everybody.

    Do as instructed above first then follow this

    Locate (C:\Program Files\Windows Resource Kits\Tools) Left click the reset command script and cheek in the general tab and confirm that the reset command script is safe then go to properties click compatibility and tick run program in vista service pack 2 mode. press ok

    Left click reset command script again and run as administrator.

    This worked a treat for me and hope it works for you all also.

  17. Great ,thanx for the spanish solution ,i cant find it, only here

  18. Lol well what i did for my win7 i just ran the reset.cmd without command prompt =D (with win vista sp2 compatibility!)

  19. It didn’t work for me for some reason. Does anyone know how to help please? :)

  20. I had this problem with Quicktime and Itunes in Windows 7 Ultimate, but followed Pauls comment (on February 25 2010) and this solved the problem!

  21. Windows 7 Ultimate

    Follow instructions to download and run the Microsoft .msi file…this created the folders under Program Files

    Copy the RESET.CMD there and SET THE COMPATABILITY TO VISTA SP2………right click…properties…compatibility and change the setting there

    Run the RESET.CMD and the furstrations will decrease IMMEDIATELY


  22. “Windows 7 Ultimate

    Follow instructions to download and run the Microsoft .msi file…this created the folders under Program Files

  26. I’m running Win 7 64 bit and have been trying this for several hours now without any luck. I have followed the instructions to the letter and everything was working great it was doing what it was supposed to do in each step. I was rather proud of my self until it came time to click on that Quicktime Player icon and then it happened. Error 46. I feel like a phucken putz. If anyone has any answers for me please pass them along. Now I’ll go back to what I’m supposed to be doing, work or something like that.

  27. this fix is a 2fer it fixed both my flash player having to be loaded every time and fixed quicktime, THANK YOU

  28. Running win7 64bit.

    And like Noody and others, I cant get it too work.
    Please help.


  29. Have to echo the frustrations of Windows 7 64 bit users. I am running Home Presmium have tried:

    1. The instructions as indicated.
    2. 2 versions of the script file .cmd
    3. Run from the command line as administrator
    4. Run from command line as not the administrator
    5. Run the .cmd files in Windows Compatibility modes of all sort.
    6. From the WRK / tools directory and system 32 directory

    and just about most other permutations you can imagine

    UAC is off

    I have rebooted.

    WTF, I paid for this software and it just doesn’t work and I guess Apple just doesn’t have to support that huh? Oh super.

    If anyone gets this solved PLEASE email me.

  30. Previous comment did not show I cannot get it to work on vista home premium

  31. I am unable to download reset.cmd. It opens as a text page with no download capability. Help.

  32. Ok I too have had a nightmare with this – tired everything above and no luck at all.
    have been pulling my hair out until I accidentally realised I need to activate windows 7 administrator account (for an unrelated issue in other software!). For anyone that may not realise this too – the administrator account is switched off by default on windows 7 (at least in 64 bit).
    To activate it you there is a good tutorial here

    Once I had done that several things started working in win 7 64 bit that weren’t working properly before : Quicktime pro included. (Other stuff some high end audio plug ins and video software).
    Is worth noting that I did manage to get Quciktime to run in XP servioce pack 2 compatibility mode on a normal user account, but when I logged as as administrator there was no need to do anything – works a treat.
    It seems there are many people having problems with this and no straight forward fix all answer. Hope that this info helps someone else out there !
    good luck !!!

  33. a very-very BIG thank you,

    Great Job!!! it is running perfectly………………..

    It really worked, anyway all Vista please ensure you turn off the User Account Control first before running the reset cmd.

    I failed initially when the User Account Control is turned on.

  34. Thanks, this is perfect. Quicktime now works.

  35. Hi All,

    Recently i received Apple Software Update for iTunes & QuickTime for my Windows Vista but i took very long hours to install but to no avail and this has been going on for a month but still i am unable to install…………………Can anyone out there help on the matter. Please help i am really frustrated.

  36. it worked!! thank you very much!^^

  37. For those with windows 7 who can’t have it to work still, here is what to do:
    1- Log in as Administrator
    2- Turn off User Account Control located in control panel/security system…(look up
    precedent post) and reboot.
    3- Log back in as Admin,assuming that you already downloaded and installed SubInAcl and the reset.cmd,the key for it to work is to have Full Control as permission for SubInAcl.exe and run reset.cmd as Administrator. You can set the permission by right clicking on the aforementionned exe,go to permission and set up full control for administrator/s,system,owner rights. Note: it’s not gonna work if you just run reset.cmd as Administrator. Oh! Also the exe and the cmd file should be set to run in compatibility mode :Vista service pack 2(sp2).

  38. Jesus Christ. Is all this really worth using iTunes or QT? I mean, I’ve got 366 other pieces of software on my Win7 x64 machine, many of them video/audio and ALL of them have installed flawlessly. This Err 46 has been around since 2006. WTF, Apple?

    SOLUTION, Win7 x64 users:
    For playback get GOM player (free)
    For editing get Virtual Dub (free)
    Obtain any one of the current (free) codec pacs

    Play, Edit, all file types.

    Dump QT. and Media Monkey and SongBird (mozilla) has got Apple beat hands down.

    I’m uninstalling iTunes & QT, if you do the same, use REvoUninstaller (free) so that you get all the left over crap, and all that automatic update crap the Apple puts on your PC

  39. Hi, i finally got quicktime to work, but it only works when i use the administrative user. It doesnt work when i disable administrator and use my main account. I followed Paul’s advice on February 25, 2010 and that got me to open the quicktime on administrative, but i guess it wouldnt let me reset the rights to the software on normal account. Im using windows 7 home premium… any tips?

  40. It works! Im so happy! I have avoided trying to sort it because everytime I mentioned ‘Active X’ people were like…oh no! Thats a reeeally bad technology! But this has worked…few bumps along the way but restart after making security amends AND THEN run the command prompt :) Ciao

  41. la solución en windows 7 es muy fácil (al menos funcionó para mi) click derecho en el icono del programa, propiedades, compatibilidad, marcar la opcion: “ejecutar este programa en modo de compatibilidad para” windos xp service pack 2, click en aplicar y luego aceptar. luego ejecutar el programa y listo.

  42. pshh i followed evrything correctly but it still gives the same message

  43. Nope, followed the procedure step-by-step in Win7 Home Premium 32-bit and still got the error.

  44. I was also frustrated but just read the last few posts, I have Windows 7 Ultimate 64-bit and tried it all! BUT – I then noticed the post above by Jenny Kim about subinacl.exe, I went in and changed the properties to allow Full Control for “users” and then used it in compatibility mode for Vista SP2 and it worked like a charm! Try this and it should work!

  45. Oops sorry the comment by Agard is the one that helped, my bad!!

  46. To echo Petey Pablo, Agard’s solution worked for me on win 7 64 bit.
    good luck guys !!!

  47. Didn’t work on my Windows 7 Ultimate 64bit T_T

  48. 1.Install subinacl.exe

    2.Download “reset.cmd” and place it in “C:\Program Files (x86)\Windows Resource Kits\Tools”

    3.Set Compatabilities on both “reset.cmd” and “subinacl.exe” to “Vista Service Pack 2″

    4.Right-click “reset.cmd” and choose “Run as administrator”

    5.Done :-)

  49. Worked great!
    Quicktime now works again.

  50. Thanks!!!
    Baudwalker solution helped me too :)
