This doesn t seem to be relevant in this case  but in case others face this problem --- make sure that if you installed 32 bit version of Eclipse  you also installed 32 bit version of JRE  Similarly  if you installed 64 bit version of Eclipse  you need 64 bit version of JRE in your Windows  Otherwise you will see the above error message as well

I faced this issue and it get resolved by following steps    Open Eclipse ini file in Notepad Search vm Delete non existing JRE path from this file as mention in below  -vm C  Program Files Java jre1 8 0 181 bin Save this file and run eclipse again

User · Answer

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

I got the same error after a Java version update  I just edited the line after  -vm  in the eclipse ini file  which was pointing to the older and no more existing jre path  and everything worked fine

User · Answer

This worked with me  Eclipse will not open due to environment variables    Let eclipse use your java vm directly   Put these lines at the end of eclipse ini  located in the directory where eclipse exe is present    -vm  lt your path to jdk jre gt  bin javaw exe   Pay attention that there are two lines  Also make sure that the -vm option is before the -vmargs option  and of course after  openFile

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