Office 2010 setup cannot open registry key unknown components

When trying to install Office 2010 on a machine that is completely messed. In the event viewer under application, under the errors, it will say "Error 1402. Setup cannot open the registry key UNKNOWN\Component\... Vertify that you have sufficient permissions...

Go to each key under, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components

Right click the main key of each component, under permissions, check replace all child object permissions with inheritable permissions from this object, apply. under owner, replace owner on subcontainers and objects, apply. and then back under permissions, check replace all child object permissions with inheritable permissions from this object, apply. now you should be able to open the subkey without errors.

OR Cheat: Do this on "Components", change owner to administrators, do this at your own risk.

Cannot install Symantec Endpoint Protection

AppData path might be wrong.
HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\AppData is listed as "%APPDATA%"
I changed it to %USERPROFILE%\AppData\Roaming

Windows 7 Auto Login box missing

Problem:
The box "User must enter a user name and password to use this computer." is missing.

Fix:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoAdminLogon value in the registry. Mine was set to 0 so it did not show. I set it to 1, and now it shows.
Once it showed up, it was already unchecked, and when I hit OK it did not ask me for a username and password. I then checked it, hit OK, then opened it again and unchecked it, and hit OK. The dialog for me to enter the username and password then appeared and worked as documented in this post."

Cannot map to any network drive or shares/RPC server is unavailable

For me it was missing one registry key
REG_DWORD "DhcpNodeType" = 1
under
HKLM\SYSTEM\CurrentControlSet\Services\NetBT\Parameters

A easy trick is, if it worked before, you can look under
"HKLM\SYSTEM\ControlSet001\Services\NetBT\Parameters"
or
"HKLM\SYSTEM\ControlSet002\Services\NetBT\Parameters"
and compare the difference.

This also fixes an issue opening Group Policy Management showing "RPC server is unavailable"

InstallRite

InstallRite keeps track of what happens to your computer before and after an installation, and it can create an installer to install on other computers.
