Hello,

 

I tried to install the new release 1.5.4.0 install and I failed at the following error message.

• PHP parameters:
  Your PHP sessions path is not writable - check with your hosting provider: C:\Windows\Temp\

  PDO MySQL extension is not loaded
   
  I already contacted the hosting provider
  Your help is greatly appreciated.
   
  Thanks,
