I'm using the VC707 fpga card and i want to transfer the data that i wrote on the DDR3 memory to a PC.
But i'm facing a couple of doubts:
1) The PCItree software works only for 32 bits system, I have a 64 bits Windows 10 PC
2) I have connected the VC707 to my computer with JTAG cable and to the power supply:
Should i keep the VC707 powered on by the PC power supply while i plug the VC707 into a PCIe slot?
3) I don't know what is the next step to be able to connect the output of my DDR3 memory MIG to the PCI e design so i can send the data from the DDR3 to my PC.

There are other available PCIe software applications available for Windows. You might check out Teledyne Lecroy Telescan PE, lspci for Windows, or others available as freeware / shareware.
For powering, when physically removing or plugging the card, you should disconnect all power - PC and VC707 power supply. If you are going to power via the PC, you will need to use the instructions in the board User Guide (as it is not a standard 6 pin power supply connector) and you will need to program the PROM on the board to load the FPGA.
For a MIG-PCIe design, including upstream bus mastering, you might consider the architecture shown in these videos:
The videos show these cores on the Gen3 capable parts, but the same cores are available in the 7-series devices as well.
