VBScript to set MSI Property
Hi All,
I am a newbie to VBScript so hopefully someone can help. I am trying to write a VBScript to dynamically set a Property in an MSI. The value of the property is a registry key value that differs from PC to PC. The script is being called from a Custom Action within the MSI. i am using Wise Package Studio 5 to create this MSI.
Here is my script so far:
Dim WShell, DISKID
Set WShell = WScript.CreateObject("WScript.Shell")
DISKID = WShell.RegRead("HKLM\SYSTEM\CurrentControlSet\Services\Disk\Enum\0")
Session.Property(DISKID) = DISKID
I've scrolled the internet and found very little that resembles what i'm trying to do.
Help please.
Scott

Change the following line:
to:
You can't use the WScript object model like this within a MSI custom action.
Change the following line:
Set WShell = WScript.CreateObject("WScript.Shell")to:

Sorry, forgot to include the error message: When running this script as a Custom Action "Call VBScript from Installation", i generate an msi error log that says:
Error 1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor. Custom action Action1 script error -2146827864, Microsoft VBScript runtime error: Object required: 'WScript' Line 3, Column 1,
However, when i run the script by itself i get:
Line: 5
Char: 1
Error: Object required: "Session"
Code: 800A0148
Source: Microsoft VBScript runtime error

Also, if you run the script by itself you will get an error relating to the object "Session" as that ONLY exists within a MSI custom action.

Thanks for your help MR B Hunter, it worked!!! I also had to amend my Session.Property line slightly to get it to work so my final code looked like this:
Dim WShell, DISKID
Set WShell = CreateObject("WScript.Shell")
DISKID = WShell.RegRead("HKLM\SYSTEM\CurrentControlSet\Services\Disk\Enum\0")
Session.Property("DISKID") = DISKID
Thanks again, really appreciate it!!. Hope this helps others too.
I'm sure there's a "Points" system operating here so i'm more than happy to award some to Mr B Hunter but dont know how. Please advise.

Hi brenthunter,
I am using the same thing as you have explained here, still while debugging through the Windows debugger the MSI goes for a toss after I set a property.
What are the condition in the installation that I have to look for, before I can set a property in the MSI using VBScript
I am trying to do it through embeded VB script code

- I presume you mean the Wise Package Studio debugger?
- No conditions are required to set a property via script.
- Which property are you trying to set? Post the code here (remembering to use the CODE tag, accessible bu clicking the button marked '<%' in the 'Reply to Message' window.)
- In which sequence does the CA containing the script execute and where (e.g. before or after InstallFinalize)?

function readFromRegistry (strRegistryKey )
Dim WSHShell, value
On Error Resume Next
Set WSHShell = CreateObject("WScript.Shell")
value = WSHShell.RegRead( strRegistryKey )
If err.number <> 0 Then
readFromRegistry= "Error"
else
readFromRegistry=value
end if
set WSHShell = nothing
end function
dbNavicligudVer = 7.28
str = readfromRegistry("HKEY_LOCAL_MACHINE\SOFTWARE\emc\Navisphere CLI\CLIVersion")
str2 = Left(str,1)
str3 = Mid(str,3,2)
str4 = str2+"."+str3
db = cdbl(str4)
If db < dbNavicligudVer Then
ans = MsgBox("We will upgrade Navicli", 65, "Error")
Session.Property("NAVITEST")=ans
Else
wscript.echo "The Current Version of NAVICLI is good"
end if
I want to set NAVITEST property here and after that I can use NAVITEST property to launch navicli upgrade

Ummm....Why not simply use the Upgrade table? That is its exact purpose...

Our product installer is separate. That installer looks for the navicli version and based on that tries to upgrade Navicli.
Its something like from an MSI i have to upgrade a different licensed tool.
