Hi Hasan.
Your case reference is 360875 should you need to contact us directly regarding this issue.
When you receive this error message, are you installing this over a network through the 'Network Installation' option on the install wizard? Or through the standard install on each computer?
Please could you re-download the ActivInspire software and try and doing a fresh install and see if the issue still occurs?
