I was trying to install msicuu2 setup in win xp when I received a Windows Scrip Host error

1. Download the SubInACL tool from this MS Site and install it. By default it will install to c:\Program Files\Windows Resource Kits\Tools

2. Go to the Start menu, choose Run and type cmd

3. Type cd /d %ProgramFiles%\Windows Resource Kits\Tools to change directories to the folder that SubInACL is installed to

4. Type notepad reset.cmd and press yes to create a new file named reset.cmd in c:\Program Files\Windows Resource Kits\Tools

5. Copy and paste the following contents into reset.cmd and then save and close it (or download it from here and rename it from reset.cmd.txt to reset.cmd):
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

6. Type reset.cmd and press enter to run the SubInACL tool (you will need to have adminstrator privileges for this to run correctly). This tool will take several minutes to run

Hope this helps!
