nvidia graphics driver install failed windows 7

existing troubleshooting pages do not help in my case. 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. Is there any installation journal? Any error log? Any additional utility NVidia has available to debug / trace driver package installation process? I would very much like to learn how can i figure out specific cause of NVidia driver package installation failure. I am very desperate to solve this issue by now. And i did not add / change any hardware since the time NVidia installation worked fine. However, earlier, this problem did not exist - i was installing and using many earlier NVidia driver packages with no problem whatsoever for years before.

Please note that this problem persists over a year in my system, with many versions of driver packages. 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. The package is downloaded directly from, with OS and videocard correctly selected prior to download. 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.
