Hello, today i start update new version propose [2.6.2 (225998) Second Life Release] but, after download, when i try install its impossible to complete installation .....opens a window that tells me that a series of files are not opened or found ( qtiff4.dll etc ...) in the folder in reality 'there is. If I choose to ignore or retry the installation is complete. I do not even work the players suggested alternatives.
