Hello, I have just recently installes Windows 7 Pro x64. Everything was great, but after a few days i noticed that I can't install any software that is based on windows installer. All setups gives me the similar errors:error 2203: C:\Windows\Installer\593406.ipi, -2147287035 or error 1305. error reading file [path and filename].msi verify that file exists and that you can access it. - I did and file exists, I also disabled UAC, but that did't helped. or sometimes it just says that can't fined specified file. I know that installers are fine and it is my systems fault. P.S. I trayed to install windows installer, but gues what, it gave me an error.
