When you install the Adminpak.msi, you receive:
Internal error: 2755.1632,c:\winnt\system32\adminpak.msi
When you click on an installed shortcut, you receive:
Temporary Directory is not found or there is not enough disk space.
This problem is generally the result of removing Full Control permissions from the Administrators group and/or the System account on the %SystemRoot%\Installer folder.
Permissions on the %SystemRoot%\Installer folder should be:
Administrators group - Full Control
Everyone group - Read and Execute, List Folder Contents and Read
System account - Full Control
Re-install the Adminpak.msi package using Start / Run / adminpak.msi / OK.
