Quicktime Pro 7 refuses to launch independently after installation of AVID MC7 / Sorenson Squeeze

Hi guys,

Hopefully someone knows a fix for this.

After installation MC7 and Squeeze, i can no longer launch QT / QT Pro. The only way i can play .mov files is via iTunes, which for me is less than desireable. So the codec is obviously there.

Please note that QT 7 (non pro) was working fine prior to installing Avid & Sorenson.

I've tried 'repairing' QT by downloading the file, but even after the repair it still refuses to launch.

Also, QT is non longer listed in the 'open with' options... Please help!

Windows 7 home x64 (latest ver.)

Could you walk us through what happens when you try to launch the Player?

If you get an error message, let us know what it says. (Precise text please.)

If you don't get an error message, let us know whether or not a button for the QuickTime Player appears in your task bar (even though the player itself doesn't appear).

Hi BN,

Thanks for replying and apologies for the delay.

Attempting to launch QT of the start button where there is an icon, prompts the user account control popup. Press yes on the prompt, it disappears and nothing happens. No error message.

Also no QT player in task bar.

I must note that when i launch QT from the start button and it prompts the user account control popup, i notice the target is in 'Program Files - Quicktime Alternative.'

I wonder if this is the cause?

🙂 Good catch!

I must note that when i launch QT from the start button and it prompts the user account control popup, i notice the target is in 'Program Files - Quicktime Alternative.'

It'll probably be a conflict with QuickTime Alternative (It's a third-party chop-down of QuickTime) and the standard QuickTime Player.

Head into your uninstall a program control panel. Uninstall QuickTime, then uninstall QuickTime Alternative. Now try reinstalling the QuickTime Player:

Does the player launch for you now?

Thanks again B. QT works fine now. Although i have lost my 'pro'status. However:

After doing everything suggested, Sorenson Squeeze refuses to launch now - whereas it was fine before. Definetly QT related - it's giving me a ''qt_cf.dll missing from link library.

I've tried resintalling both Squeeze and QT, even tried copying the .dll file to System 32 - to no avail.

There is nothing noted on the Sorenson forums about this issue.

Thanks again for your help B if this is the extent of it; i'll try and hunt down an answer!

Although i have lost my 'pro'status.

Did you make a note of your Key and Name (precisely as it appeared in the registration tab) prior to the uninstall? (Sorry, forgot to remind you about that.)

If not, the following document might be of some assistance with retrieving the key:

QuickTime Pro Key: Retrieving a lost key

it's giving me a ''qt_cf.dll missing from link library.

Doublechecking ... it's saying qt_cf.dll, not QTCF.dll? (QTCF.dll is the standard name for the dll in a QuickTime installation.)

I'll try and hunt down the lost key - not looking too good - i think the pro accoutn was activated by Squeeze as i didn't purchase it.

The exact error is:

squeeze.exe - Entry Point Not Found

The procedure entry point QTCF_CFHTTPMessageSetHeaderFieldValue could not be located in the dynamic link library QTCF.dll

I've even tried reinstalling the qtcf.dll off google searches and they too, have failed. Any suggestions?

🙂 many thanks.

QuickTime componentry is 32-bit rather than 64-bit. So if you've got a copy of the QTCF.dll, try stashing it in SysWOW64 rather than System32. Any better luck with Sorenson? If so, does the QuickTime Player still launch?

YOU ARE A GOD AMONGST PEASANTS GOOD SIR!

I copied the qtcf.dll from the QT folder over to SysWOW64 as you mentioned; it prompted me to overwrite an already existing file of the same name.

BOOM! It worked. Squeeze is up and running, so is quicktime player.

No QT pro yet though, i wonder how it got there in the first place.

If you're ever around Sydney B Noir, hit me up as i owe you many, many beers!

🙂 You're welcome!

Just one further thought. Best to keep a note that you've got a QTCF.dll down in SysWOW64, just in case you ever need to do a QuickTime Player update. The QuickTime Player installer won't "know" that there's a QTCF.dll down there, so it won't update it ... and if you get a mismatch between the version in SysWOW64, and a newer version in the standard location in \Program files (x86)\QuickTime\QTSystem\, there's scope for another sort of launch error with your QuickTime Player.

If you run into trouble with the Player launching after a QuickTime update in the future, try replacing the QTCF.dll in SysWOW64 with the newer version of the dll in \Program files (x86)\QuickTime\QTSystem\.
