How do I remove corrupted registry entries in XP? Tough nut here.

[Guest]

On a laptop running XP Pro SP2, I went to install MS Streets & Trips 2006. I
had the 2005 version on it previously. I get an error code. The support
forum from MS said to delete the following keys from the registry.

HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner.1
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult.1
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10.1

THE PROBLEM IS THIS...I can't delete, modify or edit these entries. I can
modify, create, and delete other keys, but not these. I backed up the
registry first, and when I look at the backup copy, there is nothing for
these entries. It goes from the key before these start to the key that
follows them.

I copied the backup and deliberately entered these values by hand:

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner]
@="test entry"

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner.1]
@="test entry"

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult]
@="test entry"

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult.1]
@="test entry"

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10]
@="test entry"

[HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10.1]
@="test entry"

When I tried to import the modified backup, these keys were rejected with
the claim that I did not have permission to change them.

I am under the Administrator account with full permissions.

1. I don't know why there are registry entries shown by REGEDIT that don't
exist when the registry is backed up (how can it be there but not be there).

2. How do I forcibly remove these entries so I can install MS Streets &
Trips 2006 when REGEDIT isn't letting me modify or delete the entries?

In all other known respects, the OS and other programs seem to be running
properly. These bad entries keep aborting the installation of Streets &
Trips (as they can't be modified), and I use that program a lot.

I do have a Norton Ghost image of the hard drive from after I initially
configured the laptop, but I really do not want to have to backup all the
work files, restore the backup image and then reinstall everything since then
(plus updates) to fix what should be done by editing out a few lines of text.

Thanks for your help.

Having Admin rights does not automatically give you rights to delete
registry entries. You have to go another level within Regedit and set the
permissions. Right-click on the key name and choose Permissions, then set
it to give your account to Full Control and whatever else you might need.
That should let you delete them. Do this for each of the keys you can't
delete.

I think I tried that already, but I'll give it another go tonight and post
what happens. IIRC, it would not let me do that either, but I'll make
another attempt.

Well, that doesn't work.

Just clicking on the key produces this message:

"Cannot open ________: Error while opening key."

Any attempt to modify permissions on the keys in question get this message:

"You do not have permission to view the current permission settings for
______, but you can make permission changes."

Then if I try to apply changes, I get this message:

"Unable to save permission changes on _______."
"Access is denied."


I did go to the parent HKEY_CLASSES_ROOT key. Tried doing permission
changes there. Now I get the following if I try to delete the keys:

"Cannot delete _______: Error while deleting key."

I still get the same error messages if I try to change permissions on the
individual keys.

Try it in HKEY_LOCAL_MACHINE\SOFTWARE\Classes and see if you can delete
the offending key or change permmissions there. The HKEY_CLASSES_ROOT
subkey is really just a pointer to the HKLM key. If you can do work in
the HKLM hive you might have to reboot afer you are done to have the
information in the HKCR key to update.

Use subinacl to modify the permissions for the key in question. You
can download and install subinacl from Microsoft.

SubInACL (SubInACL.exe)
http://www.microsoft.com/downloads/...56-D8FE-4A91-93CF-ED6985E3927B&displaylang=en

Now open a command prompt to use subinacl

Type the following:

cd "c:\program files\Windows Resource Kits\Tools"


subinacl /keyreg "HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner"
/owner=YourUsername


subinacl /keyreg "HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner"
/grant=YourUsername=f


subinacl /keyreg "HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner"
/grant=SYSTEM=f

Repeat the three above commands for:

HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanner.1
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResult.1
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10
HKEY_CLASSES_ROOT\Microsoft.MapPoint.WiFiScanResults10.1

Now try and delete the Registry keys.

Fortunately, I have a different XP Pro install CD other than what Toshiba
gave me I used that to install a redundant XP OS. That got me back in, and
I'm backing up the work files onto another computer now. Then, I'll just
restore a Ghost image I made when the laptop was first configured.
