Hi. Driver package 461.09 will not install, for me: right after checking compatibility of the system, it reports "Nvidia software was not installed" with the only option to close the installation window. The package is downloaded directly from NVidia.com, with OS and videocard correctly selected prior to download. However, i am _able_ to install NVidia driver manually through the device manager, from that very same package's unpacked files, and it works as in enabling full resolution of the display (1920x1080) and other features display driver is responsible for! Of course, no PhysX, no NVidia control panel and no other parts of the package are installed that way, thus i still need to complete the package's installation process - which i can't, as per above. Please note that this problem persists over a year in my system, with many versions of driver packages. However, earlier, this problem did not exist - i was installing and using many earlier NVidia driver packages with no problem whatsoever for years before. And i did not add / change any hardware since the time NVidia installation worked fine. Nor did i reinstal / change my OS. I am very desperate to solve this issue by now. I would very much like to learn how can i figure out specific cause of NVidia driver package installation failure. Is there any installation journal? Any error log? Any additional utility NVidia has available to debug / trace driver package installation process? Thank you very much for any help! P.S. Oh, and of course i tried all the usual suggestions: disabling antivirus software, closing all programs, i am always starting the setup as administrator and while logged in with administrator windows account, uninstalling all NVidia products prior to installation, etc. I.e. existing troubleshooting pages do not help in my case. I have also tried driver slimmer utility, twice (once being minimum possible install, just 3 components - core, driver, PhysX), and the utility works just fine - but install fails at exactly same point, after slimmed package's done checking system compatibility.
