upperfilter entry missing from Windows XP registry

What specifically is your problem?

I'm sorry if I was not clear.  I am trying to solve an Ipod syncing problem using the instructions provided at the link in my original mail.

The instructions called for performing a function on the "upperfilter" entry in the registry (WindowsXP).  There was no upperfilter entry, so I am unsure as to how to proceed further.

I did not know whether I should attempt to find a way to restore the upperfilter entry.  So that is my original question, given that I cannot complete the "fix" given at the Apple Support link without following the instructions related to the "upperfilter" entry.

Should I do something about the fact that there is no upperfilter entry in my registry?  And if so, is there something that I can do?

Thank you.

Have you tried uninstalling and reinstalling iTunes? Also, do you get an error message?

It depends on what function you were doing with the upper filter entry.

A common fix for CD drives is to delete upper and lower filter entries.  This makes a lot of non working CD drives suddenly start working again.

The fact you don't have an upper filter entry isn't necessarily a cause for alarm.  Some people may have it and some people may not.

But what exactly was the instruction you were trying to do with the upper filter?

If it was a delete operation as I've described above then you can continue with the instructions you were given.

If unsure post the operation you were trying to do here.

Reply to orangutang:  Thanks for your question:  "Have you tried uninstalling and reinstalling iTunes? Also, do you get an error message?"

Yes, I reinstalled iTunes numerous times, deleting iTunes using Windows XP Add/Remove Programs in the Control Panel, re-downloading iTunes, and reinstalling.

Every times I get the message in the screenshot (attached):  "The registry settings used by the iTunes drivers for importing and burning CD's are missing....."

I have deleted all other CD burning software from my hard drive.  Nothing helps.

Additionally, I am unable to get iTunes on my computer (Lenovo T60p/Windows XP) to sync with my iPod Touch.

Thanks.

To dbrunton:  Thanks for you question.  The function I was trying to do in the registry that involved the "upperfilter" is in the link included in my original and edited question.  I have attached the instructions which include the function I was trying to do (I was able to follow all the instructions up until I reached the  directions to cut the upperfilter value data and replace it, as given in the instructions.)

These instructions are from the Apple Support site in reference to the error reporting that the registry entries that iTunes uses to import and burn CD's were missing.  (Screenshot of error message attached to reply to orangutang, above)

So, did you add GEARAspiWDM?

Reply to both dbrunton and orangutang:

I have administrator rights.  I am using Norton anti-virus. I have tried turning off anti-virus before reinstalling iTunes, but I still get the same error message.

Thank you for the Fixya link.  I will look there, also.

I did not add GEARAspiWDM because I could not see how to do it, since the instructions for doing so involved using the upperfilters, which are not present.  I do not know if there is another way of doing this.

Thanks.

OK

So it looks like you have to manually enter the UpperFilter entry as per the link I gave above.

THANK YOU!

I know this has already been solved, but for those looking, instead of adding values manually, you can re-install the latest drivers from GEAR by going to their website:

This solved my drives having disappeared in Vista x64.
