Error 2755 after attepmted update, cannot install

[Guest]

This morning Windows Defender told me to update my software, which I tried to
do. I uninstalled my "outdated" version of Defender and downloaded the "new"
version from MS onto my desktop. Now I get two error messages when I try to
install:
"The system cannot open the device or file specified." I hit Retry until I
was sure it wasn't going to work, eventually hitting Cancel.
Immediately following...
"This installer has encountered an unexpected error with this package. This
may indicate a problem with the package. The error code is 2755"
Now I have no Windows Defender on my machine, and cannot install it!
Windows Live OneCare is hollering at me to install it, yet the installer
keeps giving me this message. I tried CCleaner and "Dial-a-Fix," as thats
what another message suggested. Neither worked, so I am appealling to all
you brilliant people. Help if you can.

Hello Markus;
Check Add/Remove for Windows Installer Package 3.1 version2
(3.1.4000.2435) If you don't have that installed you can get it here:
http://support.microsoft.com/kb/893803/
Then make sure your installing the Windows Defender update package from an
Admin Authority logon account.

Hi everyone.
Having the same problem but with different error message. Mine says,"Unable
to complete the update 0x8007064c. Installation source not available.
Running XP PRo SP2 with all updates. Disabled McAffe, closed all other
running programs in taskbar. Any suggestions?

Hello Deb,

Try going to WU/MU first to determine if this is a software updating issue
vs a Windows Defender bug...

You'd be better off explaining your issue from scratch than digging that
deep into the past--the product is different now, and your OS is too.

What Windows version?

What is happening?
