Nsis7z -- How do I use it?

Hi Everyone,

Sorry, I've Googled and I've searched the forums, but I can't seem to find an answer to my question.

Scenario: I have an installer I'm making, but the data is over 2GB. I used 7zip to compress some specific files down and now the installer creates properly, but obviously I need to extract the 7zip files on the users' computer for the installation to be complete.

I downloaded http://nsis.sourceforge.net/Nsis7z_plug-in and put it into my plugins folder.

I added the following lines to my .nsi file:

Nsis7z::ExtractWithDetails "Tile.7z" "Decompressing %s..."

Delete "$OUTDIR\Tile.7z"

Nsis7z::ExtractWithDetails "Sprites.7z" "Decompressing %s..."

Delete "$OUTDIR\Sprites.7z"

Nsis7z::ExtractWithDetails "Map And Sounds.7z" "Decompressing %s..."

Delete "$OUTDIR\Map And Sounds.7z"

The installer compiles fine, it runs fine and says everything worked... Except it doesn't extract my files.

Is there something special I need to do? I had thought the dll I downloaded would actually extract the files, but as far as I can tell, it doesn't and it doesn't give me any errors.

Any help is appreciated.

Thanks,

Smitty

You should specify the full path to the .7z files. (And it is probably not $OutDir, $ExeDir is the same directory as the installer if that is where they are)

Thanks for the quick reply!

I had set the outpath using

SetOutPath $INSTDIR

but just to be safe, I changed the code to be as below:

Nsis7z::ExtractWithDetails "$INSTDIR\Tile.7z" "Decompressing %s..."

Delete "$INSTDIR\Tile.7z"

Nsis7z::ExtractWithDetails "$INSTDIR\Sprites.7z" "Decompressing %s..."

Delete "$INSTDIR\Sprites.7z"

Nsis7z::ExtractWithDetails "$INSTDIR\Map And Sounds.7z" "Decompressing %s..."

Delete "$INSTDIR\Map And Sounds.7z"

That is successfully deleting the .7z files, but it still isn't actually extracting them... again no error is being displayed...

Do I need to download a standalone 7zip command line app and add it to my installer for this to work or anything?

Thanks again!

Update:

So I switched from using the x86-unicode dll and used the x86-ansi one and it is actually extracting the files now.

However, the status being displayed is off.

It says "Decompressing XX%" where the % seems to be accurate, but then it lists (0 /XXX MB) where XXX is the amount that has been extracted and the 0 always stays at 0.

Has anyone encountered that before or know of a fix? I would be fine even if there was a way to just show the % and not the #'s.

I have uploaded a new build which uses the latest 7-Zip 15.14 SDK.
