Registerbestand Export min

Many users have encountered an issue where they cannot open certain apps that previously worked perfectly fine. They have reported seeing a Java-related error message stating that ” The registry refers to a non-existent Java Runtime Environment installation or the runtime is corrupted.”

Basically, seeing this error can mean that there are entries related to a previous Java installation or that the Java location has been manually changed after an installation, resulting in incorrect registry entries. If you are one of those users trying to fix this problem on your PC, then you have reached the right location. In this article, we have discussed some solutions that have helped other users to overcome this Java error.

Solution 1: delete nonexistent path log entries

Most users have reported that deleting registry entries for JavaHome and RuntimeLib if they go to a location that does not exist has helped to fix this problem. These entries must be manually removed from the Registry after verifying the existence of the path in File Explorer.

1. Open Run using Windows and R on your keyboard.

2. Enter regedit and click OK to open the Registry Editor.

3. If prompted by User Account Control then click Yes.

Note: Before making any modifications to the registry, create a backup copy of the registry using File -> Export . While saving this file, be sure to select the Range as All. This backup can be imported later in case you have problems after the changes to revert the registry to its previous state.

4. Copy and paste the location below in the Registry Editor’s address bar.
