Hello Gajanan Ask for help the services support here http://www.tataphoton.com/customercare.aspx In USB device instalation there is very ofter the failing point installation software and device in improper order. Very often the installation process asks to insert the USB during the installation. Inserting(connecting) USB device in computer prior starting to install software may result in not predictable status. Whenever I install Windows 7 the very first step after vanilla plain operating system is installed, is installation of chipset driver. Graphics, audio and NIC driver installation follows. After initial driver installation, updates installation follows in the order that the installation procedure "suggests". Without analyzing error and warnigs data in event logs it is very hard to guess, what is the problem. Regards Milos

Gajanan, It might be due to UAC Enabled. what is the OS on the client system? If it is windows 7 , try disabling UAC and check. http://windows.microsoft.com/en-us/windows-vista/Turn-User-Account-Control-on-or-off http://www.petri.co.il/disable-uac-in-windows-7.htm Regards, _Prashant_MCSA|MCITP SA|Microsoft Exchange 2003 Blog - http://prashant1987.wordpress.com Disclaimer: This posting is provided AS-IS with no warranties/guarantees and confers no rights.
