    It had ruined my PATH variable, many programs stopped working. :( As I have already uninstalled the program, the PATH stored in path1.log was renamed to path2.log, updated with current (wrong) path and deleted. I have found some PATH in this registry: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment

    Everything worked perfectly. No difficulties with my 735-character-long PATH environment. Everything just worked. It is really great to have a command line driven MAKE capability instead of having to fight the Arduino software which tries to hold you by the hand too much. Give me CLI control instead of 'choices') anytime... Thanks to all the developers.

    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:
