The following three approaches to be tried in order have been suggested by MS. Note that you should be trying the install from and Admin acount:

1. Try using a different Admin acount.

2. Use an Admin account and install from Safe mode.

3. Use SubInAcl. The following is from an MS representative. It assumes that you have installed your system on C:\ so that subinacl is installed at C:\Program Files\Windows Resource Kits\Tools. Adjust this if you've installed XP in a different partition.

Follow the Instruction
1. Download and install subinacl from:

http://www.microsoft.com/downloads/deta ... laylang=en

2. Create a file named reset.cmd in C:\Program Files\Windows Resource
Kits\Tools folder.

3. Edit the reset.cmd file with the following content.

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f

4. Enter into CMD prompt.

5. Enter the following commands one at a time and click Enter.

cd\
cd "C:\Program Files\Windows Resource Kits\Tools"
reset.cmd

6. After a few minutes by processing subinacl, please test the problem
again.
