Finalbuilder 4 installation problem

Hi,

When i am opening Finalbuilder 4 in windows 2008R2 64 bit O.S i am getting the following error.

Unhandled exception at 0x02468c87 in FinalBuilder4.exe: 0xC0000005: Access violation reading location 0x00000004

I do not remember that i got this error while opening in Windows 7 64 bit O.S enterprise version.

Any help in this ?

Regards,

Lakshmi
