I had downloaded the 32-bit Service Pack for ChipScope on my 64-bit machine with 64-bit ChipScope installed. I was able to run the updater, but when I launch my 64-bit ChipScope, it still shows 11.1.
Did I correctly install the update?
You should not update 64-bit ChipScope using 32-bit XilinxUpdate Service Pack. ChipScope incorrectly allowed this update. If you installed this update, roll back your update using:
Start -> Programs -> Xilinx ISE Design Suite 11.1 -> Accessories -> Uninstall Last Update
In a terminal: xilinxupdate -uninstall
After rolling back your update, download the 64-bit ChipScope Update and install this Update.
If you cannot roll back ChipScope, uninstall ChipScope, reinstall ChipScope, and update using the correct updater.
