Before going to the solution, let us know why it is showing that error. If you know the problem behind this issue we can easily fix that error.
Reason 1: The most common reason behind this problem is, we are trying to install different bit version-that is, 64 bit or 32 bit version of the software. It maybe either Eclipse or Java.
Solution:
Check which version of operating system you are running.make sure you downloaded the same version of Eclipse as well as same version of Java software.
Reason 2: Configuration mistake in Eclipse.ini file
Solution:
Add this line "-vm then path of your java sdk" at the end of Eclipse.ini file. for example:
-vm
C:\Program Files\Java\jdk1.7.0_71\bin\javaw.exe
Reason 3: Special characters ( #, !, @) in Eclipse installation directory.
Solution:
Make sure you don’t have any special characters.
Reason 4: You have added JAVA path two times in PATH system variable and both the path are different.
Solution:
Remove one incorrect/different JAVA path from PATH system variable.
Reason 5: You maybe using latest version of Eclipse, but you might be using wrong version or unsupported version of Java Virtual Machine (JVM).
Solution:
To check which version of java you are using open command prompt by pressing win+R key and type cmd and press enter. Now in that console type Java -version command to know java version.
Now research whether eclipse support that version or not.
Or
You can open “readme” folder in Eclipse folder and open readme_eclipse.html to see which version it supports.
