Can I remove this? I don't know if it's something like where in XP you'd have to copy the I386 folder down for certain installs…is it?
I want to rid it to free up hard disk space.

Please do not remove the contents of %SYSTEMROOT%\Installer. If you do that, then in the best case you'll be unable to uninstall and/or repair any program installed from a Windows Installer database, and in the worst case all Windows Installer-serviced programs that have advertised autorepair capability will stop working (or at least annoy you every other minute with "Windows Installer is configuring program blahblah" dialog boxes while suspending program execution.)
There is no safe automated way to clena up a drive. Once you delete the obvious (%TEMP%, %SYSTEMROOT%\Temp, %SYSTEMROOT%\SoftwareDistribution\Download) all that's left is uninstalling unused stuff and compressing rarely used stuff.
You might also want to delete the (hidden+system) folders under %SYSTEMROOT% that hold the hotfix / Windows Update patch uninstall backups, unless you plan to uninstall windows hotfixes.

Its probably better to keep it around, but generally speaking its ok to remove it.
