Vmware ESX 3.5 Virtual Center 2.5 client on 64bit OS

Hi,
I know this is a little bit old topic, but there is still people around using Vmware ESX 3.5 version with Virtual Center 2.5 and it happens to change the management desktop to windows 7 64bit and discover that the client installed from the Virtual Center server is not supported on 64bit OS

Around in internet there are some articles with a workaround, but they are old and outdated, the solution is really simple, download the latest version of Virtual Center 2.5 (I found Update 6c) like a .ZIP file,
unzip it, you'll find in there the client setup, that one is working on 64bit clients :)

Here the link where I downloaded it (you need to be logged on the site to open it) :

WSUS computer not reporting status : Error 0x800b0001

WARNING: Digital Signatures on file C:\WINDOWS\SoftwareDistribution\SelfUpdate\Default\wuident.cab are not trusted: Error 0x800b0001

This is the error I had in my c:\windows\WindowsUpdate.log while I was trying to get my XP computer updated by the WSUS Server I just installed.

After many time spent trying to fix the error in many way I discovered the problem was simply my WSUS server an old version while the XP machine was serching for a most recent WSUS.

So the solution was simply:

1. install WSUS 3.0 SP2 Over the previous WSUS 3.0 installation
2. install the WSUS patch: KB2720211
2. reboot the server

once the server was up and running:

3. on the client run this script (found in internet) :

net stop wuauserv /y
net stop bits /y
net stop cryptsvc /y

RMDIR /S /Q %systemroot%\SoftwareDistribution_Old
ren %systemroot%\SoftwareDistribution SoftwareDistribution_Old

regsvr32.exe c:\windows\system32\wuapi.dll /s
regsvr32.exe c:\windows\system32\wups.dll /s
regsvr32.exe c:\windows\system32\wuaueng.dll /s
regsvr32.exe c:\windows\system32\wucltui.dll /s
regsvr32.exe c:\windows\system32\msxml3.dll /s
regsvr32.exe c:\windows\system32\wuaueng1.dll /s
regsvr32.exe c:\windows\system32\wups2.dll /s
regsvr32.exe c:\windows\system32\wuweb.dll /s
regsvr32.exe c:\windows\system32\atl.dll /s

net start wuauserv /y
net start bits /y
net start cryptsvc /y

wuauclt.exe /resetauthorization
wuauclt.exe /detectnow
wuauclt.exe /reportnow


And after few minutes I seen my client asking me to install new updates, and on the WSUS server the pc appeared with its status. Problem solved :)
