Acrobat Reader X MSI installation asks for Internet Explorer 6 or greater

Hello,
 
I just recently found the enterprise deployment guide, and wanted to deploy Acrobat Reader X via Active Directory, so users without administrative privileges *should* be able to install it.
 
The problem is, when a user without administrative privileges tries to install Acrobat Reader X through via the Software control panel in Windows, the installer stops with the error message, that reads something like this (I use a German Windows, so my translation might not be exactly like the english counterpart):
 
Adobe Reader X Internet Explorer 6.0 or greater required. An upgrade for Internet Explorer is available at www.microsoft.com
 
Since I try to install it on Windows 7 64bit, I already have a IE greater than 6.0.
 
Here is what I did:
I downloaded the MSI install file from the Adobe FTP server and copied the file to a network share.
 
In the group policy I added the MSI as a package in the user configuration, and published it.
 
In my Windows 7 I now open the "obtain software from network" (again it's my translation from my German Windows), and choose to install the published Acrobat Reader.
 
The installer window opens, and I choose to continue the install.
After a few seconds, the installer stops with the error that IE6 or greater is required.
  
If I sign in as an Administrator, the installation via the Software control panel works. But since I wanted to publish the software via Active Directory so Users do *not* need to be Administrators, this is not really helpful.
  
Am I doing something wrong, or did I miss anything?
