IISHelper dll of InstallShield 2009 Support folder issue in WindowsServer 2008.

Hi,

I am stuck-up with one major issue; I guess one of the InstallShield Support DLL is causing this issue.

I have a WebApplication which is packed using InstallShield 2009 Basic msi project. Both Installer and Application are working fine for Windows Server 2003 R2(SP-2) .
Issue: Not able to install my product on Windows Server 2008 R2(SP-1).

I think this issue is due to IISHelper dll which is present in ‘C:\Program Files\InstallShield\2009\Support’ folder.

Error:
