Answer 1

Check the eclipse.ini file and make sure there is no -vm option there that is pointing to a non existing java install now. You can delete the option to let Eclipse figure out what java install to use or change it so it's pointing to the new install.

Answer 2

Step 1

My computer > properties > Advance system settings

Step 2

environment variables > click New button under user variables > Enter variable name as 'PATH'

Copy the location of java bin (e.g:C:\Program Files\Java\jdk1.8.0_121\bin) and paste it in Variable value and click OK Now open the eclipse.

Answer 3

I had this problem before and I solved by :

Right click my computer -> properties -> Advanced system settings.

In both sections :

• User variables for "YourUser" &
• System variables

Update the PATH by adding to the end of it a ";" and your java bin folder location , mine was "C:\Program Files\Java\jdk1.7.0_51\bin"

If there is no path then create it using the NEW button, set "Variable Name " to PATH and "Value" to your java bin location.

You can replace your PATH if there is no need for it

NOTE : THE FOLDER BIN SHOULD CONTAIN javaw.exe

Answer 4

I have tried everything, and finally deleting the -vm options worked for me.
