Xilinx iMPACT (the FPGA programmer) bugs:

On one version, it can load the project it saved, but then crashes when you go to program. So you have to scan and reload all the data files every time you start it.

Later version, failed to program the chip at the last stage of the process. Diagnosed that over phone tag where the user was non-technical and on a machine not connected to the Internet. Exact same chip as above.

Another later version has different iMPACT bugs than that first version above, but right now I haven't been able to get it to work on any Win 8.1 machine so I don't remember which bugs it has.

You have to change out a certain DLL for POST windows 8 in order to get ISE to behave and not crash randomly. YAY! Xilinx said they didn't care but somewhere on their support forum there is some kind soul who said what dll to rename (they have two versions of the DLL in the install anyways but they did not use the win 8 one by default and refuse to patch).

This is entertaining. I've used Xilinx's tools for a while, almost exclusively on Linux (CentOS usually). I thought that renaming/symlinking libraries to get things to work was something only Linux users needed to do, and I figured this was just because Xilinx tests more on Windows (makes sense). If these kinds of problems also affect the Windows versions, then, I don't even know what to say. At some point you just can't make excuses for this stuff anymore.
