I found that some people have problems with installation of Dragon Saga client – unable to install client on disk different from C:\ and this is completely weird. I don’t know, maybe issue already solved, if not, then you can manually extract all files from msi:
1. Create .bat file (or use cmd) with following command
where you can correct msi packet path and extraction path “TARGETDIR”Code:msiexec.exe /a "Y:\DragonSagaInstaller-0.1.29-20110216.msi" /qb TARGETDIR="Y:\ds"
2. Run .bat
