_DirSize.tmp file is reporting the incorrect folder size.
The following warning is present within the MailEnable Diagnostic Report:
COM+ Registration Directory IWAM_MACHINENAME or EVERYONE group do not have access to the COM+ package registration directory (which is the default setting for a Windows 2000/2003 installation).. The IWAM_MACHINENAME account needs access to this directory in order to run COM+ applications. C:\WINDOWS\Registration
IME_SYSTEM account does not have read access to the Microsoft Windows "registration" folder.
Run the installation kit and perform the upgrade to see if this resolves the warning in the Diagnostic Report or manually assign the IME_SYSTEM account "read" permissions on the: C:\Windows\registration folder.
