When you are logged on as a standard user and you run a Microsoft Installer (MSI) package, you may receive error messages similar to the following messages during the installation phase:
Error 1913, Could not update the file... Verify that the file exists and that you can access it.
1321 The Installer has insufficient privileges to modify this file: filename
1401 Could not create key: registry key
Other error messages may occur, depending on whether the change was made in the registry or the file system, but the error message usually reports a lack of privileges on the part of the user or service to perform an action relating to the installation of the software.

The Installer has insufficient privileges to modify this file: path\filename
For example, you may receive an error message that is similar to the following:
Error 1321 The Installer has insufficient privileges to modify this file: e:\pfiles\msoffice\office\excel.exe
This behavior occurs because SYSTEM has been denied access to the directory, file, or registry keys necessary to install the software.
The Office XP SP3 error message may occur if access to the CD-ROM has been denied for the locally logged on user. This behavior can occur if the Restrict CD-ROM access to the locally logged on user only policy has been enabled or if the policy has been set in the registry. The current user will not be able to install Office XP SP3 or to update from the CD-ROM.
In order for Windows Installer to finish its function with elevated privileges, the file system and the all registry keys must allow SYSTEM full control over these components to allow for installations to take place.
To resolve this behavior, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
