    This software works exactly as advertised. Just keep in mind that it's command line, so I wouldn't call it easy to use. I had no problems with installation, not even with the PATH variable. If you are worried about PATH simply save the contents in case you have to restore it later. You can use the command "path > path.txt" to copy the contents to a text file.

    This software is nice... Assuming you can get it to work for you. I read some of the reviews and I didn't want to take the risk of winavr overwriting my path directory, so I unchecked that option for the install. However, I couldn't use things like avrdude without changing the directory and running the executable. But, there is a work around that I want to share that could save someone a lot of time if they don't want to take a risk like me. Create a file called "winavr.bat" in "C:\WinAVR-20100110" with the following contents: set PATH=%PATH%;C:\WinAVR-20100110\bin;C:\WinAVR-20100110\utils\bin cmd If you want to use WinAVR, just simply double click on the .bat file and you'll be able to use avrdude, make, etc. I do not take credit for this. I would have just given the link, but I would never expect someone to click on a link in a review. Go to section 2.1.4 of this page:

    This deleted my windows PATH environment variable. It should not be possible to download harmful software like this. See SuperUser "How to extract environment variables from system restore point, Windows 7 64-bit" for instructions on how to recover your deleted PATH variable.

    Apparently the developer is not aware that Windows software should be installed in 'Program Files' or 'Program Files (x86)'. By default WinAVR is installed at the root. He allows installation to the standard directories, but when you install to these directories, the tools no longer work (probably because the developer does not know how to handle spaces and '('/')' in paths. These are allowed in Windows but not in Linux. The easiest fix for this error is to install in standard directory, and then create a symbolic link at the root. (something like: mklink /D C:\WinAVR C:\Program Files (x86)\WinAVR), and then fix up the environment variables to point to the right place. Also, the avr-gcc -mstrict-X option is not supported in the latest trunk binary, which ends up breaking a lot of make files.

    CAUTION: The installer clobbers %PATH%. There's a path1.log file stored along side the uninstaller which you can use to rescue your %PATH% Environment Variable, but it will be deleted if you uninstall (in that case, your only recourse is to do a System Restore).
