I just downloaded Windows defender and when it was done downloading it didn't
start downloading. So I found the program file and when I tryed to open it
Windows asked me what it should open the file with. I did a little reasearch
and I found that it should open with msiexec.exe and when I found this
program. I had Windows try to open it and when I did that a window came up
that has things about what ceirtan things meen to this program, but it
doesn't install.I don't know what it should open with or what I should do. If
anybody can help me with this please do.
 
Check the following registry key:

HKEY_CLASSES_ROOT\Msi.Package\shell
(Default) REG_SZ Open,Repair,Uninstall

HKEY_CLASSES_ROOT\Msi.Package\shell\Open
(Default) REG_SZ &Install
MUIVerb REG_EXPAND_SZ @%SystemRoot%\System32\msi.dll,-36

HKEY_CLASSES_ROOT\Msi.Package\shell\Open\command

The value should be:
(Default) REG_EXPAND_SZ "%SystemRoot%\System32\msiexec.exe" /i "%1" %*
(Make sure you watch all the quotes)

Also, make sure C:\Windows\System32\msi.dll is registered:

regsvr32 C:\Windows\System32\msi.dll (do this from a command prompt window)

Also, check SERVICES.MSC Windows Installer service, Startup should be Manual
