Install BootCamp update 4.0 on Windows 7 x64 returns error

Question

Hello,
I have a problem updating BootCamp software on Windows. Updating from 3.2 to 3.3 or 4.0, from ASU or from manual installation, returns this:
https:// picasaweb.google.com/lh/photo/-w77Vf1cQrlarNb_LUz7fNct5nxxnOU3qWXwGpPvXwI?feat=directlink (spanish)
Basically, it says that I'm using a network resource that is not available, and tell me to pick a "BootCamp64.msi" file
If I set the file, it returns this:
https://picasaweb.google.com/lh/photo/_tqfhSNKK1wBmojjR7kWy9ct5nxxnOU3qWXwGpPvXwI?feat=directlink (spanish)
It says the file set is not valid msi for installing Boot Camp Services, and tell me to find a file called "BootCamp64.msi" on a folder ready to install Boot Camp Services
This for 3.3 and 4.0 versions.
In the log, it says...:
Info: Found Boot Camp x64 version 3.2
Info: BootCampUI failed to install 64 bit Boot Camp patch. The install returned 1603
Info: BootCampUI is exiting. The install returned 1
I know how to manually install the drivers, but what I want is update bootcamp.
Details:
SO W: Windows 7 x64 Updated
SO OSX: Mac OSX 10.7.3 "Lion" Updated
Mac: iMac 21.5" (Late 2010 I think) 500GB, 8GB RAM.
This problem appeared from the first day I installed Windows 7.
I also have a log file from de msi generated with the command "/l*v c:\log.txt",it doesn't make me happy to make it public, but I've attached.
Thanks,
Alberto Salazar
P.S. : I'm spanish, so my english might be difficult to understant. Sorry.

Uninstall Boot Camp
Run Microsoft Installer Cleanup Utility
Install 4.01
Sometimes you update by first removing the old version
You may want to run CCleaner as well.
CCleaner Optimization Cleaning
Start: run
Type: %TEMP%
Select All - send to Recycle Bin
Those two should be done as regular household cleaning maintenance

The Windows Installer CleanUp Utility is designed to allow you to safely remove Windows Installer settings from your computer in the event of a problem. Although the Windows Installer is designed to be very robust, it is possible for Windows Installer to become damaged if:
Your computer's registry becomes corrupted
You or someone else inadvertently changes a registry setting used by the Windows Installer, resulting in a problem
The installation of a program that uses Windows Installer (for example, Microsoft Office 2000) is interrupted
There are multiple instances of Setup running simultaneously, or an instance of Setup is "blocked"
