I do okay when downloading the "Tixati 64-bit installation icon" from your site on my computer but when I try to install it onto my 64-bit computer I get an error message of: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item". Can anyone tell me what I need to do to get permission so I can install Tixati to my computer? I appreciate any help anyone can give me!
