Quicktime installation errors during upgrade

I have been getting the below event details while trying to upgrade quicktime.  I have tried all permission changes, I am an administrator, and I have uninstalled all previous versions.  However, this error keeps stopping the installation of the new version.  Any ideas?

what about going to control panel --> user accounts --> create a new administrator user , log off and back on as that new user and then try to delete those registry keys making sure to see if you can try to take ownership and full control of those registry keys with that new account ?
Try a few things :

1. Open up regedit and navigate to that registry key and right click on it and go to permissions of that registry key and make sure that you have full control of the registry key.

2. Un install quicktime including the upgrade etc

3. make a full back up of your registry

4. get ccleaner ( www.ccleaner.com )

5. Run the registry cleaner in ccleaner and fix all the issues it finds making sure to run it a few times and you can also save the changes before fixing them.

6. download quicktime ( stand alone installation ) and re install it.
Also it may be an idea to use the windows clean up utility described on this page :

Thanks for the comments.  I have tried both of your ideas and the same problem still exist.  Basically, I just need to figure out how to delete registry entries that I cannot take ownership of.  Can I do this at some command line level?  As for the options above, ccleaner worked, but it also could not delete the quicktime registry entries that there are no permissions to.  The eindows clean up utility did not list quicktime as an installed application even though it has existing registry entries.  I assume this is because I have already uninstalled quicktime.

So if you have any ideas on how to get rid of these protected registry entries, I think that will do it.
Re install quicktime over itself and then try the above methods again ( including the windows clean up utility )

I have tried and the install get to the point of registering keys and then fails giving me a message that I do not have permissions to the key.  I am already the system administrator, so I do not know what else to do.  I fell like I may need to format.
can you take ownership of the key ? if you right click on the key and go to permisions does it tell you who has owner ship of the key ( If not then what about closing regedit and going to control panel --> folder options --> disable simple file sharing

basically the last checkbox and apply that then go back to reg edit and see if you can view who has owner ship , then if its not administrator you need to make administrator have full control / ownership of the key(s) and then delete them.

I cannot take ownership.  Looking at the permissions of the key the current owner box list "unable to display current owner".  If I try to take ownership, I get a message telling me that I cannot. I am sure if I could get ownership, it would fix this problem.
if you go to control panel --> admin tools --> event viewer, does it display any error messages regarding you trying to delete the quicktime registry keys or quicktime or anything like that, if so what are the event id's for those events.
can you delete the registry keys in safe mode or even for that matter un install quicktime in safe mode ?
envoygcAuthor Commented:
no, nothing is logged in event viewer while trying to delete keys.  only the event id related is the one above that I get every time I try to install quicktime.  this is driving me crazy.  could the registry be corrupt?  if so, can that be fixed?
have you got system restore enabled, if so maybe go to a restore point before you installed quicktime.
envoygcAuthor Commented:
i have not tried safe mode.  i will have to try that and report back.
Found this :

1. Go in the registry editor. The top most folder listed i
Right-click on this folder and select PERMISSIONS from the menu.
2. Once there, look through the permissions listed and make sure that
Administrators and System are both listed. If they are not, pleas
refer to
the bottom of this write-up under "Conditional Step".
3. If they are both listed, make sure that both have Full Control
checked on ALLOW. If they are not yet checked, click in that box an
APPLY. This will put the proper permissions through the registry an
set you up for a good installation. Once finished with this area selec
and close the Registry Editor.

Conditional Step
If you've found that System and/or Administrators are not listed i
permissions section, you will need to add them. To do so, click th
Button and in the following screen type System or Administrator
on which is missing. (You may only do one at a time). Once typed
select the
CHECK NAME button which will end up highlighting the name and then yo
select OK.

I think you are onto something with the new account.  I logged in with one of my other accounts and could delete the keys and install the program.  I will work later on removing/migrating my profile completely, but this looks like the fix.

I will report back.  Thanks, John

BTW - I had already tried before the permission setting on the HKEY_Classes_Root folder.
here is what apple says about it :


Also there was an mskb here :


 but it only applied to windows 98 and ME thats why i suggested the new account because they were saying that it was due to profile corruption or the registry being corrupt and to use regscan to restore or fix the registry.

Not sure what the equivelant is in windows xp though. Probably system restore.
