A suitable JVM could not be found. Please run the program again using the option -is:javahome

Got this error on websphere install on windows box

The fix i did was , i went to the command shell and checked the path of java 

c:\> java -version

now the path of java i gave as a command line parameter 

c:\>install.exe -javahome path to java  

and it works.

Its a java path problem , alternatively you can try going to environment variables inside mycomputer and try creating a variable named Java_home = path of java
