eclipse won't start - no java virtual machine was found

Question

Eclipse was running fine yesterday (and has been since I installed it about a year ago). Now all the sudden I\'m getting the following error on startup:

\"A          


        

Answer 1

eclipse.ini:

--launcher.defaultAction  
--launcher.XXMaxPermSize  
256M  
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize<br/>
256m  
--launcher.defaultAction  
openFile  
-showsplash  
org.eclipse.platform
-vm
C:\Program Files\Java\jdk1.7.0_21\jre\bin\server\jvm.dll<br/>
--launcher.XXMaxPermSize  
256m  
--launcher.defaultAction  
openFile  
-vmargs  
-Dosgi.requiredJavaVersion=1.7  

That worked for me. It doesnt have to be on the beginning, but surely it cant be at the end of the file.

Answer 2

This happened to me also. And I found the javaw.exe in C:\Windows\System32 got deleted after the windows update. Copied one more time and Eclipse started all fine.

Answer 3

you can also copy your JRE folder to eclipse directory and it will work corectly

Answer 4

My solution is Include JDK's "bin" Directory in the PATH

To edit the PATH environment variable in Windows 7/8/10:

1. Launch "Control Panel" ⇒ (Optional) System and Security ⇒ System ⇒ Click "Advanced system settings" on the left pane.
2. Switch to "Advanced" tab ⇒ Push "Environment Variables" button. Under "System Variables" (the bottom pane), scroll down to select "Path" ⇒ Click "Edit...".
3. Copy the JDK bin directory from JAVA folder and paste to "Edit..."

Answer 5

I came across same issue y'day, with PATH etc configured correctly. It can be opened from command line, just now working by a double click.

And it was working now, by just "Run as administrator" :)

Answer 6

I had the same problem. I my case it was a program i've install that had destroyed the PATH env variable.

so check your PATH environment variable.
