I recently purchased a MTNL Teracom 3G Jadoo Data Card. And it does not work on Windows XP (64 Bit).I tried it in Windows XP (32 Bit). It works perfectly. But as my processor is AMD Phenom X4 (64-Bit) and I have 4 GB of RAM (2 Chips of 2 GB Each), I use a 64 Bit Windows XP. If I use a Windows XP (32 Bit), only 2 GB of RAM is used. I need 64 Bit Drivers for Windows XP 64 Bit. I had tried calling the Head of the MTNL 3G Department and they are telling me to come to BKC. As I use a desktop PC, its impossible to carry it there. And as it as government office, they won't have a 64 Bit System to check on. So they will just test it on a 32 Bit System and Show me that this is working. Can anyone help me ? I need 64 Drivers of MTNL Teracom 3G Jadoo Data Card so I can use it on my Windows XP 64 Bit.
