Hi there,

I have 2 Windows 10 machines, with the same version of Eclipse and a centralised SVN repository that holds the Java code. One of the computers has a slightly more old version of the JRE and the Run/Launch program is successful.
The other computer has JRE and the Run/Launch fails with 'Error: Could not find or load main class Main.Galactica'. The clssspath is : C:\Program Files (x86)\Java\jre1.8.0_251\bin\javaw.exe -Dfile.encoding=Cp1252 -classpath "C:\Users\andyh\workspace\Galactica\bin" Main.Galactica

I am going to try and use the same JRE on both, but I cant see that being the issue. Anybody got any ideas whats going on. The Java code is the same.

I don't know how complicated your application is but is it possible to copy the compiled application from the good computer to the the other and start it without help from Eclipse from the command line?
I can see you are using a 32 bit version of Java is that deliberate?
What version JDK have you used to compile is it the same on both computers?

Are you able to launch a simple Hello World Java Program with the same JRE ?
