Common AA3 Opening Problems

MAGIX Vegas is Not Installed

When trying to open your AA3 file, you get the error "Can't Open AA3 File Type". Customarily, this means that MAGIX Vegas is not installed on %%os%%. Your operating system cannot associate your AA3 with MAGIX Vegas, so double-clicking the file won't work.


Tip: When you have another program installed that you know will open your AA3, you can select it from the other programs listed (see "Show Apps").


Obsolete Version of MAGIX Vegas

It is possible that your version of MAGIX Vegas isn't able to open your ATRAC Audio File file due to incompatibility. Installing the latest version of MAGIX Vegas from Magix Software GmbH is recommended. Your ATRAC Audio File file was probably created by a newer release of MAGIX Vegas than what's currently installed your computer.


Tip: Find clues on the correct software version by right-clicking your AA3 file and clicking "Properties".


Conclusion: The majority of AA3 file opening issues are due to not having the correct MAGIX Vegas version installed.
