Might have to enable the show compatibility files function or whatever. Google it. And learn how to use the operating system in your own darned computer lol.
lol It did that for me. I had to turn it back on by logging into my admin user and re-enabling it. I think you have to cut and paste ALL Compatibility Files across your entire system before you disable UAC. That way, you can access them.
I never had any issues with compatibility files, I never even heard of that until people posted about problems with it. I probably never encountered the issue since I disabled UAC from day 1.
I also asked about a dozen times whether or not you set Winrar to run as admin (and posted on the last page how to do that; find winrar.exe, right click to properties, and set it to always run as admin) and you never answered that. I also asked if you tried using Windows' built-in .zip extractor instead. Right click any zip file to properties and set it to open with Compressed Folders (for XP) or Windows Explorer. (for 7)
Well no poop, you selected the folder instead of the .zip file.
However, extraction appears to be working fine; you get a 12.4mb folder from there. In other words, you shouldn't need to worry about extraction anymore as the folder appeared to be extracted properly. Now just move/copy the folders into place; tracks, objects, and environments. (Into your NL install directory.) Unchecking the Read-only box probably won't do anything, but it's worth a try, so uncheck it before copying/moving the folders over.
