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).
This is absolute crap. Instead of appending something to the PATH environment variable (Win7, 64bit) this installer overwrites it, leaving the rest of your system completely screwed. DO NOT INSTALL
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: www.newae.com/sidechannel/cwdocs/installing.htmlokpoijoiu
