Spark doesn't launch\run at all

Spark simply doesn’t launch for me. when i click the icon it looks like the computer is loading for 1 sec then it does nothing. anyone got an idea?

i tried reinstalling it a number of times and Java as well. i work on windows 7.

You can wipe your Spark profile and start with a fresh one. Spark profile is here

C:\Users\username\AppData\Roaming\Spark

If you need your history, copy this folder:

C:\Users\username\AppData\Roaming\Spark\user\username@servername\transcripts

And copy it back after you start with a fresh profile.

You can also try the latest Spark build http://bamboo.igniterealtime.org/artifact/SPARK-INSTALL4J/shared/build-665/Insta ll4j/spark_2_7_0_665.exe
