I'm pretty sure its there, you just don't see it, send me a screenshot of the folder.
Anyways, u just have to run the install.bat w/ Admin.
Try this tweaks as well, use this command lines on the CMD (run it as administrator as well) and type this:
bcdedit /set disabledinamicticks yes
bcdedit /set useplatformclock no
Delete any previous Nvidia driver you have installed, even the one in Asus website is shit. Go yo Nvidia, search for the 441.41 drivers version of the 1660Ti laptop, download, then fresh install. It's one of the most stable versions for this graphic card.
For AMD driver, the best one is the oldest one on the Asus website. Download AMD cleanup utility yo remove any previous driver you had installed and then install the one i told you from Asus.
