Hi, first of all, sorry by my bad english XD. My loader allow ATT to run in Vista 64, i think this is the safests way because it dont allow any unsigned driver to be loaded, only the ATT one. The loader dont enable testgisning, dont instal anything, it only use old atsiv method and binaries to load ATT driver in run-time. Notes: Disable UAC and Windows Defender. I apreciate any feedback Download Link: http://rapidshare.com/files/150928433/ATTLoader.rar Aditional instructions to use with UAC and Windows Defender enabled (Thanks to Risco): 1. Place the loader in the ATT folder 2. In control panel go to scheduled tasks 3. In right hand pane select "create task" 4. Type in name then tick "run with highest privileges" 5. Click triggers, click new then choose "at log on" 6. Click actions and browse to attloader 7. Click conditions and untick everything 8. Close everything 9. Log off windows, then back on and ATT will load automatically! NOTE: Dont forget to uncheck "Load with windows" option from ATT wherever you use or not UAC.
