I have tried adding the tools.jar file manually (as suggested in another question's answer from StackOverflow), but this did not resolve the issue. This error first occurred with the last update of Java on my laptop. Any suggestions as to how I would go about eliminating this error message & getting Eclipse to work again?

1What problem were you *originally* trying to solve with this? – nitind Oct 02 '20 at 23:46

Install and use the JDK, not the JRE. – Mark Rotteveel Oct 03 '20 at 11:18

unfortunately, using the JDK yielded the same error message @Mark Roffevel – Cassiopeia Oct 03 '20 at 15:08

@Casseiopeia Which version of the JDK did you install, and which version of Eclipse are you using? – Mark Rotteveel Oct 03 '20 at 17:37

The filename is incorrect it should have .jar not .jar.jar
