"Learn to use"-rollback, installation failure when installing the. NET Framework 4.6.1 __.net

When you install the. NET Framework 4.6.1 (which is also the case with 4.5.1), a rollback situation occurs during the installation process, which eventually prompts the installation to fail, and finally pops up as the previous image page. At this point, follow the steps below:

1, in the installation of the failure of the window click "Log File", with the Internet Explorer to open the log file.

2, pull to the bottom of the log file, found in the red paragraph

3, in the corresponding directory to find dynamic link library (. dll file), right-click-> Property-> Security-> Advanced-> to change all user permissions to Full control.

4, and then retry the installation: This situation still occurs (but the modified directory is not the same). Repeat 1-3 steps.

5, install again. Generally successful.

Ps: Why not change file permissions at a one-time

Because everyone's situation is not the same, should refer to the log file to modify more accurate, although more cumbersome.

If you have any questions please comment and welcome the exchange.
