EMC 9.1 leave registry errors after installation

[Big_Dave]

Prior to installing EMC 9.1 rev c I did a registry scan clean to ensure that all was well. My registry after the cleanup process had no errors prior to the installation of EMC 9.1 rev c. After the installation it contains 5 regisrty errors (7 keys and 8 entries) per Registry Cleaner. While everything appears to be working correctly for now, it does show the EMC 9.1 does not handle the registry updates and entries properly.

 

And, let the registry experts now chime in!

I'm starting to be suspicious of using reg cleaners lately with all I've been reading here and on other boards about the changes they make specifically in Vista. I feel relatively safe with XP but until more is known about Vista, I'm not using any unless I have to.

I have another test to do. I'll do a uninstall of EMC 9.1 when the registry is clean and see what the results turn out to be with the registry. I'll post the results. What we want out of this is for a better prodcut to be produced by Roxio.

The uninstall of Roxio EMC 9.1 rev c left the following registry errors:

 

4 registry errors

Erroneous registry data: 20 keys and 18 entries

Left over data: 9 keys and 9 entries

 

That's probably not too bad considering the number of progams and entries in the registry with Roxio EMC 9.1 rev c Suite. Still, I think Roxio and make it better for all.

What program do you use to clean your registry?

Lately I have been using JV16 PowerTools. RegCleaner is another product although it doesn't detect errors as well.

I found a few after installing, but they are easy to correct manually by editing the registry.

 

One example is

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\VCU3DcheckApp9.exe

 

which wrongly refers to VCU3DcheckApp.exe (without the 9) after the installation

 

Easy to correct both the key name and the path in that key.

 

Can't remember the others, but they were of a similar nature. Similar errors were in v. 9 (posted some time ago on these boards).

 

Another key written during the install of 9 or 9.1 is not an error, but a nuisance:

 

HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers\RXDCExtSvr

@="{0FB82570-BB2D-23D3-8D3B-AC2F34F1FA3C}

 

causes shortcuts to folders on the MS Office toolbar, when clicked on, to open the 'move or rename audio files' window instead of opening the folder (it hijacks the default behaviour). Easy to overcome by deleting the key.

 

 

 

Some comments on registry cleaners:

 

If you use a registry cleaner, you should examine each item it flags up, to see if it really is an error and if so whether it can be fixed manually (generally if you let the cleaner fix it, it deletes the key or value, which is not always the right thing to do).

 

Some entries that many cleaners flag are not real errors, just that the cleaner does not recognise some types of correct entries, simply because the software's tests do not include all possibilities. Common examples include paths to .exe files that have added command switches at the end of the line: often flagged as file missing or similar because the cleaner thinks that the switch is part of the file name and then reports it can't find the file. Letting the cleaner 'fix' that type of entry would be heading for disaster.

 

It is wrong to assume that the best registry cleaner is the one that flags up the most 'errors'. In fact one could argue that the opposite is the case: a poorly written cleaner will flag as 'errors' perfectly good entries that don't fit in to what the software (inadequately) tests for. I have tested some cleaners that claimed to be the most thorough and indeed identified over 1000 'errors' where others found less than 50. However, the vast majority of those, if I'd allowed that cleaner to 'fix' them, would have made most of the software on my PC inoperable. Fewer than a dozen turned out to be real errors that could be fixed manually (e.g. wrong path for a file or as for EMC mentioned above, wrong file name, hence reported as missing file). Some others were just redundant entries such as empty keys or those left over after unistalling some application, that do no harm at all since they are never accessed. The last category would be the only ones I would ever let a cleaner 'fix' (i.e. delete).

 

You should read the rseults of a scan with a registry cleaner, much in the same way as you would read a newspaper: don't believe all you read, often the 'facts' reported are wrong or misleading :-)

 

It is also more of a myth than reality that redundant registry entries adversely affect PC performance (unless your sense of timing is so acute that you notice a difference of a few milliseconds).

You're right about some registry cleaners. Some are better than others and it may take multiple passes to get everything cleaned up properly. Sometimes two different products may be needed to make the registry nice and tidy. Taking a backup prior to any registry modification with such tools is the prudent and safe thing to do.
