I'm struggling to understand why the Discovery Accelerator 10.0.3 Client requires UAC to be turned off in order to be installed.

The DA & CA client install doesn't offer a "Run as administrator" option.  The user account that is logged in on this Windows 7 computer during the install is in the local administrator group.  When I run the setup with UAC at the default setting, the following error appears:

"The installer has insufficient privileges to modify this file: C:\Program Data\regid.1992-12.com.symantec\regid.1992-12.com.symantec_Enterprise_Vault.swidtag."

Why, oh why, does the installer not have permissions to modify a file IT is installing?  Furthermore, why in the name of every system administrator does an install, while logged in as a local administrator, require UAC to be disabled?  Rather than work with the heightened security that Windows 7 offers as a means of protecting systems from viruses and malware, why must we do the very thing we shouldn't have to do just to install a product - as an administrator?!

I verified this by disabling UAC, restarting the computer and trying the DA client installation again - with success.  Removing DA, putting UAC back to the default setting, restarting the computer and trying to install the DA client again results in the above error.

Seriously, Symantec.  Where is the "Run as administrator" option so we don't have to go through this just to install your product?  Now we have to make sure the user is an administrator, disable UAC, restart, install DA, reset UAC to default, and restart again just to install a product once...  and repeat the process when the next verison of CA or DA comes out.
