Reasons and solutions for 1603 error when installing java

Error situation:

I have installed java1.7 before, and now I want to upgrade to version 1.8. I uninstalled 1.7, but I am installing java1. 8, jdk can be installed smoothly, but additional jre frequently prompts 1603 errors.

Solution:

jre is written in java and will call the java program to install it. Due to the previous java1.7 The environment variables still exist, causing the jre installation to fail with 1603.

Go to the environment variables and delete the previously configured java variables, then restart the computer and reinstall.
