Problems With My Custom Installer

I created a custom installer a bit ago and it works fine but I am having a few issues with it.

Unlike a package installer it is slower at installing and at times the users get error codes with the installer not extracting the files or somewhat related.

This is how the installer works:

• It deletes all the temporary files on the computer in case the installer was previously installed
  • Then the installers moves a .zip file to the users computer from the resources folder
  • After which it extracts the .zip
  • Then it moves the files it extracted to the correct director(y)(ies)
  • ...and finally it just deletes the .zip and the extracted folder off the computer

I have used installers before their job in around 5 - 7 seconds.

They move the same files as mine, but my installer that was custom made by me does the same exact job in around 40 seconds or so. On my computer... For the users, it could last for up to 3 - 4 minutes.

Those installers do the same thing as mine (could be a different procedure)

...So I was thinking, how do they do that? Maybe there is a way for me to avoid moving the .zip and unpacking it.

Is there a way I could possibly place the already extracted folder into my Resources folder and move it to the computer.

Or maybe add the folder to my Solution explorer and install the files and folders from there.

Also... Without usage of .zips or any extracting tools.

• There might be other solutions to my problem that I am not aware of. Please help me!
