Well from the error message its saying the cache directory is not wrtiable which looks like the C:\Windows\TEMP\ folder so you should ensure that folder is read and writable for the webserver. If you can't change the permissions of that folder then you should create a silverstripe-cache folder in your installation and make sure thats writable. Then reload the cms by visiting

The trouble is Zend stores temp files in C:\Windows\Temp on Windows, but SilverStripe doesn't set it's temp location, since it's a third-party library. Creating a silverstripe-cache directory in the project probably won't help either.

Please make sure the Users group has write permissions on C:\Windows\Temp and you should be fine again. You can edit the permissions by going to the "Security" tab after right clicking the folder in Windows Explorer, and going to "Properties".

Thank you
adding permission to the temp folder worked
