Listing installed applications on Vista 64-bit with WMI
There’s a few sample scripts around to list the installed applications using WMI. The trap on 64-bit platforms is that the 32-bit and 64-bit installation information is stored in different places in the registry, and you need to be clever about telling WMI that you want the 32-bit data instead of the 64-bit.
Here’s some VBScript that will list first the 32-bit and then 64-bit installed applications:
strComputer = “.” Const HKLM = &h80000002 Set objCtx = CreateObject(“WbemScripting.SWbemNamedValueSet”) objCtx.Add “__ProviderArchitecture”, 32 objCtx.Add “__RequiredArchitecture”, TRUE Set objLocator = CreateObject(“Wbemscripting.SWbemLocator”) Set objServices = objLocator.ConnectServer(“”,”root\default”,””,””,,,,objCtx) Set objStdRegProv = objServices.Get(“StdRegProv”)
WScript.Echo “32-bit Applications” WScript.echo “——————-“
Call GetApplications
objCtx.Add “__ProviderArchitecture”, 64 objCtx.Add “__RequiredArchitecture”, TRUE Set objLocator = CreateObject(“Wbemscripting.SWbemLocator”) Set objServices = objLocator.ConnectServer(“”,”root\default”,””,””,,,,objCtx) Set objStdRegProv = objServices.Get(“StdRegProv”)
WScript.Echo “64-bit Applications” WScript.echo “——————-“
Call GetApplications
Sub GetApplications
’ Use ExecMethod to call the GetStringValue method Set Inparams = objStdRegProv.Methods_(“EnumKey”).Inparameters Inparams.Hdefkey = HKLM Inparams.Ssubkeyname = “Software\Microsoft\Windows\CurrentVersion\Uninstall\”
set Outparams = objStdRegProv.ExecMethod_(“EnumKey”, Inparams,,objCtx)
For Each strSubKey In Outparams.snames
Set Inparams = objStdRegProv.Methods_(“GetStringValue”).Inparameters Inparams.Hdefkey = HKLM Inparams.Ssubkeyname = “Software\Microsoft\Windows\CurrentVersion\Uninstall\” & strSubKey Inparams.Svaluename = “DisplayName” set Outparams = objStdRegProv.ExecMethod_(“GetStringValue”, Inparams,,objCtx)
if (“” & Outparams.sValue) = “” then ‘wscript.echo strSubKey Else wscript.echo Outparams.SValue End iF
‘Inparams.Svaluename = “QuietDisplayName” ‘set Outparams = objStdRegProv.ExecMethod_(“GetStringValue”, Inparams,,objCtx) ‘wscript.echo Outparams.SValue
Next
End Sub

Oracle Databases on Windows Vista
Vista got released in November last year, and I’ve now come across the first “big” application that doesn’t currently run on Vista.
Oracle will support Windows Vista but most likely not completely until the second half of 2007!
I would have thought a company the size of Oracle could dedicate a few resources to running their stuff on the beta releases of Vista, so that it wouldn’t be such a big step to get it all working.
At least I don’t do much Oracle stuff, but it does happen occasionally (like today), where it is a problem.

Who was that “David from Aberfoyle Park” who rang in last weekend to talk about his experiences using Windows Vista?
