Problem: 
          I am using Windows Vista, and I can't get First Class to install properly. 
       
       
         
          Windows 
            Vista adds extra security with its User Account Control (UAC). If 
            you are having problems installing First Class, you might need to 
            turn off the UAC, reboot, install First Class, turn on the UAC again, 
            and reboot again. Specific instructions:

            If 
              you have installed First Class, uninstall it.

            Click 
              on Start > Control Panel.  
           
         
        -  
          
 
            Under 
              User Account and Family Safety click 
              on Add or remove user accounts. 
                
               
           
         
        -  
          
 
            Click 
              on one of the user accounts, for example you can use the Guest account. 
               
           
         
        -  
          
 
            Under 
              the user account click on the Go to the main 
              User Accounts page link. 
                
               
           
         
        -  
          
 
             
              Under Make changes to your user account 
              click on the Change security settings 
              link. 
                
               
           
         
        -  
          
 
            Under 
              Turn on User Account Control (UAC) to make 
              your computer more secure, "uncheck" the Use 
              User Account Control (UAC) to help protect your computer 
              check box. Click 
              on the Ok button. 
                
               
              
             
           
         
        -  
          
 
            You 
              will be prompted to reboot your computer. Do so when ready. 
           
         
        - Now install 
          First Class. You should be able to do so without a problem.
 
        -  
          
 
            In 
              order to re-enable UAC, go through the same steps, but "check" 
              the above checkbox and reboot.
