you don't need any software to transfer files from the fone to computer, the SE File manager is not required at all I tried it, useless & slow.
Simply plug the IR adapter in the USB port, then wait for the device found dialog, then install drivers
Check if the infrared service is on in services.msc, if off then turn it on
now turn on IR in you cell, & place it near the IR adapter connected to PC, your PC will detect & ask for drivers for K500i series modem, ignore it or use windows update ot find them
then right click on the IR icon in the system tray & configure it to accept files from other computers, & specify a folder, by default it's desktop
After that click on a file in your fone, select Send via inreared, & place it near the adapter
I use the same trick with my K500i
IR is not supported by SE File manager for T610
