I'm working in InstallScript MSI project.
I set my app in InstallShield to install Windows Installer 3.1 before loading dialog [SdWelcome] to install my app.
When I install my app in Windows XP Pro SP1 (default version of Windows Installer is 2.0), first, my app install Windows Installer 3.1. And then loading dialog [SdWelcome] & many dialogs after that to install my app.
Here is my problem: after I press button [Install] in dialog [SdStartCopy2], a message box with error code  occur: "The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or the Windows Installer is not correctly installed. Contact your support personnel for assistance. " (content of this error like this link: http://consumerdocs....0722&sliceId=1)
When I set value for property [REBOOT]="ReallySuppress" and build my project by InstallShield 2010, I fixed this error in Windows XP Pro SP1.
But when installing my app in Windows 2000 Pro SP4, I saw this error again.
I wonder if the reason is my InstallScript MSI project (I use this project type to install my app in RECORD mode & SILENT mode). Cauz I developed the same app by Basic MSI project and I didn't meet this error (I can't use this project type to install my app in RECORD mode & SILENT mode).
How can I fix this error ?
Any suggestions'll be appreciated.
