I am totally confused!! Magix Service Center tells me "serial number already used." Another says "Product has not been registered yet." Sony Creative Software Registration goes blank screen when I attempt "Missing Orders and Serial Numbers." I don't know what else to do! Is there a phone number to reach you or Sony Creative Software to fix this issue? I have the serial numbers sent with my CD.

The very annoying elevated privileges problem has been around for years - I have it happen every 2 to 3 weeks.

The workaround was outlined on Sony's Sound Forge forum a couple of years ago - this is what I copied at the time and use to solve the issue each time it occurs:

- Open regedit
- Find the key named ''HKEY_USERS\XXXXXX-XXXX_Classes\VirtualStore\MACHINE\SOFTWARE\Wow6432Node\Sony
Creative Software"
- Delete the key
- Close regedit
- Soundforge now works again

Note : in the key name above, 'XXXXX-XXXX' is a number which may be unique to
your machine.

The only variation I make is to only delete the 'Sound Forge 11' entry in the RegEdit menu in the LH menu column.

SF11 should then open as normal as it will create a new RegEdit entry. Everything will be okay until it decides to spit the dummy again in a couple or few weeks time - then just repeat the above process.

As is always the case with RegEdit editing, be very careful as there is no Undo (as far as I know). Consider first saving the entry to be deleted - just in case.

I hope that this is the solution to your SF11 problem.

After the new Creator update, I can't delete any registry keys, and SF11 is dead to me. It won't open. Has Magix come up with a fix yet?

Not that I'm aware of. I have gone back to using the free daw, audacity. At lease it works.

The elevated use privilege registry tweak should fix. This happened on both SF Pro 10 and 11 (at different times) on my Win 10 PC... soon after a Win 10 auto update.

"In the Registry Editor, navigate to the following directory:

HKEY_USERS > [user SID]_Classes > VirtualStore > MACHINE > SOFTWARE > Wow6432Node > Sony Creative Software > Sound Forge [Pro or Audio Studio] > [Version Number] ... right-click to delete the 'version number' folder.

Your 'user SID' may be different... on my Win 10 Dell XPS laptop, the reg. folder was:
HKEY_USERS\S-1-5-21-1127706934-2234140011-1683470176-1001_Classes\VirtualStore\MACHINE\SOFTWARE\WOW6432Node\Sony Creative Software\Sound Forge Pro\10.0\

FWIW, The 64 bit Sound Forge Pro 12 has not exhibited this issue... at least not on the beta test builds. I currently have build 21 installed, which I believe is the just released retail version. It's very snappy, opens in less than 2 sec. and supports VST-3 plug-ins.

This forum thread caught my eye - I've had the same problem for a long time with SF 11. In case it helps anyone, I'm attaching a screenshot from the old Sony Customer Service page (which no longer exists) that described the workaround that others have mentioned above.

Thinking of upgrading to SF 12 just to finally leave this annoying bug behind.

held off buying SF upgrades for years because of this problem.. Just purchased SF 15... sadly.. problem still persists...

is there a fix ??
