Is there a way to do a 7zip exe and have a registry file that executes after the contents have extracted? I've read of sfx archives and such, but I've never found a guide on this. Thanks so much!

Check out this guide for help.

Here's what I would do. You will need to do a few things:

1. Create a file in UTF-8 format named config.txt, do not include in archive
2. Get the 7zS.sfx file from the topic posted above, do not include in archive
3. Create a batch file, temp.bat, and add it to the stuff you are going to archive
4. Get your .reg file, put it in with the stuff you are going to archive

config.txt should look like this:

Be sure to save it as a .txt file with UTF-8 encoding, not ANSI.

temp.bat should look like this:

Obviously change setup.exe to the name of your setup program in the archive, and change /switch to whatever parameters you need to do a silent install. Also, temp.reg should correspond with the name of your .reg file.

So when you are done creating temp.bat and have added both it and your .reg file to the files you plan to archive, you can then begin compressing them with 7zip. The output will be a .7z file. We'll call it setup.7z. Take this file, setup.7z, and put it in a directory with 7zS.sfx and config.txt.

Launch a cmd window from this directory and use the following commands:

This will merge the three input files into one self-extracting .exe, which will launch the batch file we created after extracting the contents of the archive. If you want to make the self-extracting .exe to be silent while it is decompressing the archive, you will have to follow the instructions in the topic I posted above to hack the 7zS.sfx file with reshack.

If you need further clarification, I will do my best to help.

Thank you so much. Very clear, excellent explanation. Thanks for the link too; I had not seen that one.

I have some files that need to be placed in system32. I also have the files that I want to place in programfiles. I can build the exe, but I think I am building it incorrectly as it does not work. I thought as a workaround to only use one 7z as the guide shows would be to place the system32 files into the winamp folder and then move them after the extraction has taken place. What am I doing wrong?
config.txt has same relative contents as shown in the guide. I found the 7za.exe example in later pages on the thread you posted a link to; normally to allow this, I should install 7zip first or should I just place the 7za.exe in system32 folder?

copy /b winamp.7z + sys32.7z + 7zS.sfx + config.txt winamp.exe

I ran my tmp.bat for testing, and it worked fine. It would be nice to have this all into 1 file executable though via 7zip. In this case of testing my tmp.bat, I do have a copy of 7za.exe in the system32 folder, and I have 7zip installed (having 7zip installed or not is something I am curious of as well). It has to be something simple I am missing. I know how to do this type thing with rar sfx archives. Thanks in advance to those willing to share knowledge on this!

Hey there

I'm not overly experienced making self-extracting 7zip archives when compared to some others on the forums, but I will do my best to help you out. One thing I can tell you right now is that 7za.exe is a standalone console program, there is no need to have 7zip installed to use it.

Putting 7za.exe into system32 seems to be a wise idea. I might have to use that on my future install discs.

Anyway, since you say the batch file works, then the solution is within very close reach. If you try making a single .7z archive, then maybe you could make two folders within that archive, for example Winamp and Sys32. Just drop all your files in there, uncompressed (they will get compressed when they become a .7z archive). Then, try the following commands in the batch file to extract the contents (and do the rest of your tasks):

tmp.bat

Give that a try. I think that is what you are trying to do, right? Lol I'm a little tired (2 midterm exams tomorrow, and a couple school projects due this week). Anyway, like I said I don't have a whole lot of experience with this stuff but hopefully that will work. It might not even be close. We'll cross our fingers.

Thanks for your reply. Good luck with your tests! I've got a big one tomorrow. This works if these particular folders don't have subfolders. If winamp for example has a subfolder, the copy /y *.* doesn't get the subfolder and its contents.

Try xcopy (xcopy /? in cmd window for syntax)

Wow, it seems there would be a more efficient way of doing this. I thought two 7z files could be used or something. Anyone?

Is everyone here clueless as I am on this? It would be great if someone doesn't mind helping me
