Honored ContributorHi,
Currently the only fix is to run NIOS 9.1 EDS using "Run As Administrator" option. I've also reported to Altera that nios2-app-update-makefile.exe should be signed to prevent UAC warning. They have also had similar problems in the previous versions of the command line tools and they have fixed those. slacker wrote: "I don't think the OS you're using is officially supported". Well, it depends which document you are reading. The readme.txt from Quartus 9.1 states: "The Nios II Embedded Design Suite is supported on the following operating systems and versions: Windows XP SP2 Windows XP Pro X64 Edition Windows Vista 32-bit Windows Vista 64-bit ... " But in the Altera's Download Center only the 32-bit Windows versions are listed under NIOS tool. And the NIOS 9.1 Release note (which was released this weekend, after two weeks of the actual release of the software :-) states that XP (64) is supported but no Vista 64-bit ... So go figure. My own situation is that I'm running Windows 7 64-bit. Although I'm able to run NIOS 9.0 IDE nicely, the new NIOS 9.1 EDS fails to show "NIOS II Hardware" option, so I'm not able to run any NIOS applications with it. And this problem turned out to be only with Windows 7, which is not supported at all. I could use the legacy NIOS 9.1 IDE, but because the programming tools produce a non-bootable EPCS flash file, I cannot use 9.1 at all. So I continue using NIOS 9.0 IDE, but I have 9.1 installed so that I get the USB Blaster driver from 9.1, which finally works without tricks under 64-bit Windows ... Regards, Jari
