When we will create installer of any application by default it will not write the installation
path (InstallLocation) in the registry when we will install that installer. For this we have to
insert the InstallLocation in the CustomAction table of msi database.
Step 1: and we have saved it at c:\app folder.
Create a vb scrip file save it. Suppose its name is SetInstallLocation.vbs
Vb script code is as follow:
Option Explicit
Dim InstallerObj
Set InstallerObj = Wscript.CreateObject("WindowsInstaller.Installer")
Dim DbObj
DbObj = Wscript.Arguments(0)
Dim MsiDbObj
Set MsiDbObj = InstallerObj.OpenDatabase(DbObj,1)
Dim QueryStr,CommandObj
QueryStr = "INSERT INTO `CustomAction` (`Action`, `Type`, `Source`, `Target`) VALUES ('InstallLocation', '51', 'ARPINSTALLLOCATION', '[TARGETDIR]')"
Set CommandObj = MsiDbObj.OpenView(QueryStr)
CommandObj.Execute
QueryStr = "INSERT INTO `InstallExecuteSequence` (`Action`, `Condition`, `Sequence`) VALUES ('InstallLocation', 'NOT Installed', '1500')"
Set CommandObj = MsiDbObj.OpenView(QueryStr)
CommandObj.Execute
MsiDbObj.Commit
Wscript.Quit 0
Important points about table columns:
1. Action: It is the any name of the action.
2. Type: It the type of an action. To set any property type is 51.
