The difference is in elevation of privilege. In normal mode, an admin-level
user will not have access to write to or alter designated system folders.
Using the elevated "run as admin" prompt will allow this. It is a
self-elevation that allows a process the necessary permissions to make
changes in protected folders. This is done to prevent malware from usurping
admin privileges from the user's account level to access/alter system files
without the user's consent (commonly seen now as the UAC prompt). This was
implemented due to the common user practice of using administrator accounts
for day to day operation. Software created for Vista runs from a virtual
folder in a user account's appdata directory, where the user has sufficient
write/change privileges without elevating. Older software is often
hard-coded to write to the actual Program Files or System folders, and that
requires the extra elevation of the "run as admin" as they are protected
