Install Java Error 1603

Error conditions

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

Solution

jre is written in java and will call the java program to install it. Since the previous environment variables of java1.7 still exist, jre cannot be installed. , failed 1603.

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