Can't Re-innstall Package After Unstallation

Hello dear,

I uninstalled Auth and Auth_HTTP packages. Then, when I install again
those packages, I got this message:

No releases available for package "pear.php.net/Auth"
install fail

It is same for Auth_HTTP package. I've no idea how to install again.
I'm using XAMPP version 1.8.0 on Windows 7 OS. I think pear package
manager is already included in XAMPP. So, I don't need to install pear
package manager, right?

Coz, I can check my pear version in command line using %pear version
command. This is my pear version:

PEAR version: 1.9.4
PHP version:5.4.4
........

But when i check all available packages using %pear list-all, the
error message came out:

Security Error: Will not write to
C:\Users\User\AppData\Local\Temp\pear\cache\xxxxxxxxx.cacheid as it
symlinked to C:\Users\User\AppData\Local\Temp\pear\cache\xxxxxx.cacheid
- possible symlink attack

So, I tried to upgrade pear using %pear upgrade command even my pear
is latest version (i,e, 1.9.4). The error message come out again:

Error getting channel info from pear.php.net: Security Error: Will not
write to C:\Users\User\AppData\Local\Temp\pear\cache\xxxxxxxxx.cacheid
as it symlinked to
C:\Users\User\AppData\Local\Temp\pear\cache\xxxxxx.cacheid - possible
symlink attack

Please help me. As you know, Auth and Auth_HTTP packages are really
useful for authentication. I don't know how to do now. Hope, you'll
help my problem.

Thanks for your time.
