Unfortunately, that won’t work. It will require the batch logic. If the user is running in normal mode, (backup & purge my %DOSDIR%) when it gets to the part it will install the packages, they report “Not installed” even if they are installed. This is because all package information has been purged. So, all conflicting packages must be uninstalled prior to purging the %DOSDIR% or they will fail to install due to conflicts. > >> Without going through a package list comparison and removal.

If FDI uninstalls every package that is currently installed, but doesn’t include any custom packages, then it will probably be removing things the user does not want touched outside of the %DOSDIR%. > >> An install or upgrade if installed option would be nice.

So, if someone were to download version 1.0 of BLAH from sourceforge and drop it in they’re C:\games directory. If FDINST tries to install version 2.0 of a blah.zip package, it will fail. Since it has no package information about blah.zip, it will also fail to remove it the old version. A user is forced to hunt down every file associated with BLAH, then to install the new version. > > Mateusz > > > ------------------------------------------------------------------------------ > _______________________________________________ > Freedos-devel mailing list > Freedos-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/freedos-devel ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
