If it's asking for a disk then it means an entire data tome is missing from the download.

I'd recommend restarting the downloader to see if you can pick that up.

diablo 3 an unexpected error occurred while updating required files-58

If you've pre-downloaded the digital version of the game in these languages before AM CEST ( AM GMT) on Saturday May 12, you must obtain the new downloaders to be able to install properly once the game is released on May 15.

We apologize for the inconvenience, and ask that you please let friends and acquaintances know so they can begin downloading the working installer that's now available. Obtain the new Diablo III digital downloader using the links below 2.

Similar to "An unexpected decryption error occurred", the error 108 can be caused by corrupted, damaged or incomplete installation files.

This can often times be caused by closing the downloader early.

We've recently become aware that playing Diablo III with the latest Catalyst 12.4 drivers for ATI cards may cause some visual artifacts for specific hardware configurations.

This issue affects users of ATI Radeon HD 2400, 2600, 2900, 3400, 36 graphics cards under Windows Vista and Windows 7.

If that doesn't help, delete the folder Battle.net/Agent (probably in your Application Data or App data directories, use search if you can't find it). This is helping people with some updating issues, don't know if it will fix yours. You can also disable firewalls as this can cause network problems (remember to re-enable them again afterwards though).

I would love to know why these programs are crapping out on me or if my computer is total garbage. Each group or usernames give full control in all options (the EDIT and Advanced buttons too). Please anyone face this problem knows how to fix this ?

With this i was able to launch the launcher and start patching, logged in and played abit. Please post this on D3 tech support forums cus i cant. Thanks So basicly when i tried logging into the diablo beta this morning, the launcher said there was an update, after about 30 min it was still at 0%.

When restarting the downloader, make sure to select the same download folder that you did before.
