MSI Installer: Class not Registered Problem

Hi All,

I have made a MSI Installer using Visual Studio 2010, I have used following properties for this installer to behave like administrative rights. The main purpose of setting the following properties is to install the MSI Installer without asking any credentials.



ALLUSERS = 2

MSIINSTALLPERUSER = 1



After setting these properties for the MSI Installer, its working and installing fine on all other Operating Systems except Microsoft Windows7 Professional.

On Windows 7 and 8 its working fine only facing problem in case of Windows7 Professional [i have tested for 32 bit for now]



I am getting an error

Class not registered [Exception from HRESULT:0x80040154 (REGDB _E_CLASSNOTREG)]

[Class Not Registered, HRESULT: 0x80040154]

Please help me to solve this error.



Thanks in advance.
