What Should The Upperfilters And Lowerfilters Settings Contain?

[VikingByNature]

Dear All,

 

Ok I have 2 problems which I have spent days trying to solve by following every step possible provided on these discussion groups. Here are the errors and the steps I have taken so far to try to fix them:

 

1. When I tried launching EMC9 Classic, I received a "Dragon engine initialization failed" error message.

- Tried running "REGSVR32 ...\Dragon30.DLL", "REGSVR32 ...\DragonFire30.DLL" and "REGSVR32 ...\DragonRs30.DLL", all 3 registered successfully and rebooted my system but still the same error message.

2. When I run D2D, its icon displays "No Recorder" even though my CD/DVD drives are available.

- Renamed the "LowerFilters" value to "BACKUP_LowerFilters" with the multistring value "PxHelp20 DRVMCDB DLACDBHM".

- Installed the latest PX Engine, which put "PxHelp20" back into the "LowerFilters" value but this, unfortunately, caused the CD/DVD drives to disappear so I had to delete "LowerFilters".

 

As it stands now, I have no "LowerFilters" value but the "UpperFilters" value has the multistring value "GearASPIWDM" which is the GEAR burning engine needed by WinAmp V5.541. Also, all my CD/DVD drives are present.

 

Any advice on what to do next would greatly be appreciated! Thank you.

The actual values for the filters are hardware and software specific and what may be on one machine probably won't be on yours.

 

Microsoft have this to say on the matter:

 

1. Click Start, Start button, type regedit in the Start Search box, and then click regedit in the Programs list.

 

User Account Control permission If you are prompted for an administrator password or confirmation, type your password, or click Continue.

2. Locate, and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM.

3. In the right pane, right-click UpperFilters, and then click Delete.

4. Click Yes to confirm the removal of the UpperFilters registry entry.

5. In the right pane, right-click LowerFilters, and then click Delete.

6. Click Yes to confirm the removal of the LowerFilters registry entry.

7. Exit Registry Editor, and then restart the computer.

Note After you remove the UpperFilters registry entry and the LowerFilters registry entry, you may lose functionality in certain programs such as CD recording programs. In this scenario, you must reinstall any affected programs. If the problem recurs, contact the program vendor to determine whether an update is available for the program.

It's used in a particular case when you 'lose' the CD drives from the system and it's nothing to do with the failure of the Dragon Engine to load

Is it possible for you or someone else, who owns a copy of EMC9, could forward to me their screenshot of the registry entry

Here's mine. Don't know if it'll help you.

The Dragon Initialization error, was an error that I remember seeing posts about, when EMC 7 and 7.5 were new. It was resolved by downloading Napster, to replace the one loaded with EMC, then reboot. Once Creator Classic opened successfully, Napster could be uninstalled, if so desired.

 

Anyway, have you tried the "clean install", here?:

For Vista, scroll down to the bottom of that link, and click on the Vista link.

A clean install is something I would prefer not to perform unless it is truely the only workaround. Is it possible for you or someone else, who owns a copy of EMC9, could forward to me their screenshot of the registry entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} or an export of that in .REG format? I have a gut feeling I am very close to solving this problem myself.

Indiscriminate deleting of Upper and Lower filters is probably not a good idea.

Those filters are instructions for either a class of devices or a particular device.

If you remove them then you're removing those instructions.

 

The PXengine update fixes those filters for Roxio among other things.

 

I would remove Roxio completely using the directions Bruce pointed to.

Then reboot Windows and make sure that it sees the drives.

If it doesn't then try this.

If it does then go ahead and reinstall Roxio.

Hopefully that will make them work.
