This is All-in-One ADB, Fastboot and Drivers, the 15 seconds installer for 3 most needed PC tools for Android. No need to download that big SDK tool for 3 small things. I originaly made it for my Kurdish friendAnGrY DuDe in early 2013. I saw another ADB installer on XDA, but it wasn't good enough for me so i'm finaly posting it here. It's very small and fast installer for tools and drivers.
15 seconds ADB Installer v1.4.3
ADB, Fastboot and Drivers
System-wide: ADB and Fastboot are installed to %SystemDrive%\adb directory, and added system-wide path.
Current user only: ADB and Fastboot are installed to %UserProfile%\adb directory, and added path for current user.
CMD can use ADB and Fastboot from any directory.
Drivers are installed to system - no need to install them from directories.
Installer automaticly decides if install 32-bit or 64-bit drivers.
If anybody got problem with detecting device, go see picture guidehowto_driver.zip
If installation fails, then post here contents of "adb-installer.log" from desktop. (if there is any)
If you have problem with driver enumeration in Windows 8.1 install updateKB2917929
If you have older Google USB Driver installed, please uninstall it from Control Panel before installing new
If you have previously installed it as system-wide and now you want it current user only (or vice-versa), it won't remove it, you must do it yourself. (at least for now)
