Trying to reinstall a HP 5250 Printer/scanner. Downloaded the update package from the HP site, but it will not install and gives this error: MS VC90.MFC version 9.0.21022.8 public key token "1fc8b3b9a1e18e3b" Fatal Error MSI.netdevicemanager40 I downloaded the HP problem solver but it didn't help after many tries and reboots. I found on the web a reference to "go t microsoft and download the windows installer cleanup utility. you can click this link: www.support.microsoft.com/kb/290301 " When I go to the microsoft link it refers only to Office - but yet other web references also point to this cleanup tool for installer. Does anyone know if the cleanup tool work on Win 7 64 bit?
