An error occurred while installing. NET Framework 3.0.

The official release of. Net framework3.0 makes it hard to download and install, but it fails.
The log content is as follows:

[11/07/06,12: 09: 51] WIC install the Program : [2] error code 1603 for this component means" A critical error occurred during installation "
[11/07/: 09: 51] WIC installer : [2] setup failed on Component WIC installer
[11/07/: 10: 09] wapui: [2] depcheck indicates WIC installer is not installed.

This mistake is rare.
Finally, find a solution.
Previously, my machine was added to the domain, but I used a local administrator account to log in. The Administrator may not have the permission to "manage audit and security logs" for security reasons.

Use an account with the relevant permissions to execute the installation program. (Because it is the permission of the local administrator, the permission problem was ruled out from the beginning, resulting in a delay in resolving the problem ).
I hope this will be helpful to my friends who have encountered similar problems. To experience the benefits of. Net framework3.0!
