First, please make sure that you already extracted DomDomSoft Manga Downloader zip file to new folder.
DomDomSoft Manga Downloader is a portable application so normally you don’t need to install. But in Windows 7 and Windows Vista, it has UAC feature that block application from writing in system partition (usually C:\).
To fix this, you have two options:
1/ Easy way:
Please move DomDomSoft Manga Downloader program to another partition such as D:\ or E:\ (non-system partition).
OR
2/ Hard way:
Run DomDomSoft Manga Downloader with admin privilege: Right click to .exe file or shortcut, choose Properties, then choose Compatibility, then check Run this program as an administrator –> OK.

You should do this with Config\Updater\DomDomSoft Updater 2.exe too.

Why do I always get this message? The program works just fine for me. And I’m using Windows XP, not Vista or 7.

Where did you download DMD? Did you try to re-download the installer of latest version?
Thanks.

I have tried both methods and I still get this error that it cannot write to disk. If I install the newest version, is the authentication key still valid?
