powershell_ise hangs on start up

when the ISE does not start and the window pos up but does not render try the following tip. It worked for me :

create in C:\Windows\System32\WindowsPowerShell\v1.0 folder a text file

named

powershell_ise.exe.config

and put in following contents :

xml version=”1.0″?>

<supportedRuntime version=”v4.0.30319″/>

This tip from a technet forum saved my day on Win7 32 Bit machine.
