Hello,
"Access denied" is windows error telling you that you can not 
  write to the file that is being used.
AmiBroker instance is running 
  therefore you can not change the application. You need to close all running 
  instances
prior to installing beta.
Best regards,
Tomasz

    hi, 
     
    I received the 64-bits version of Windows 7 on a new computer. 
    Installed Amibroker up to 5.2 (32 bits version) and want to install the 
    latest beta now.  Go to the devlog page and download the latest beta. 
    The run it. It starts off asking to extract it in C:\Program Files 
    (x86)\Amibroker 
     
    I press  Next 
     
    then I get a pop-up window (FreeExtractor Error): An error prevents 
    this program from continuing: Could not extract the current file: access 
    denied. 
     
    Anyone see this? What to do about it? 
     
    thanks, Ed
