OS Windows 7, 64 bit
It appears that the last round of Microsoft updates caused some errors? deletion? of an important file folder .... App Data\Local\Temp\7zS63E\Setup.\Setup\blocksysuser... on my Toshiba L750 laptop, I have seemingly corrected most of the problems, but I cannot reinstall all the software for my HP Photosmart Printer. System Restore proved to be not up to the task of repairing the problem, and running sfc \scannow did not detect any apparent errors?
Is there anything I can do to correct this problem, short of running my 5 rescue disks to reinstall everything?
Assistance would be greatly appreciated!
