QuickTime failed to initialize on Windows 7

Sorry about the delay in getting back to you, cotton. Illness, family commitments, being away from an internet connection, and sundry personal failings kept me offline for a while.

🙂 glad to hear you got things working again.

same as jhartigan... deleted / installed several times... in admin i have been able to use itunes but as soon as i restart the computer it comes up with ERROR 2093 whether in admin or user account. Have followed cottons example and while sometimes have been able to open itunes successfully i find I am still unable to load itunes after restarting computer. Never had a problem with Vista sp2

Hi, I was getting this problem on Windows XP/SP2.
It started happening when I upgraded to QuickTime 7.6.5.

After (unsuccessfully) trying what was recommended on the following threads.

I decided to do my own investigation, after trying a few different things I
DOWNGRADED to QuickTime 7.6.4 and this solved the problem !!

NOTE TO THE QuickTime 7.6.5 product manager
===========================================
I am currently assuming that the developers of QuickTime 7.6.5 have broken it.
As if you downgrade to 7.6.4 it works straight away WITHOUT even rebooting XP.

Being a programmer I have done some under the covers investigation.

I have had a cursory look inside the DLL using a DLL viewer and the exported library calls are all in place.

I also looked at the registry using regedit for
HKEY LOCALMACHINE -> SOFTWARE -> APPLE COMPUTERS INC -> QuickTime

I compared this for both 7.6.5 and 7.6.4 and there seemed to be the same types of entries.

I also compared the Window PATH variable and this seemed to be the same for both versions too.

THEREFORE - I currently believe that something else has changed between 7.6.4 and 7.6.5 to create the DLLs path that is used by QuickTime.

Can you guys please look into this ?
My assumptions may not be correct but downgrading seemed to prove something has change between versions.

Also for those who want an older version of QuickTime I got mine from
