I've enabled this line in httpd.conf
...and you saved the file and restarted Apache as we can only guess at what you have done or are even trying to do.
Also the zen-cart web site may be of more help with the archive file types than here.
As far as I recall there is no gzip binary in XAMPP - gzip is a *nix thing.
I downloaded from the internet several zip files containing various binary archive files like gzip and zip some time ago for my 1.6.8 XAMPP version, I placed the binaries, after extracting, in the
apache\bin folder in a folder called simply
zip - then I call the particular archiver binary I need by reference to this location - for example
C:\xampp\apache\bin\zip\gzip.exeThe zip archives containing various zip type binaries that I downloaded are:
zip232xN.zip
unz552xN.exe
gzip124xN.zipSo an Internet search may find the latest releases of these files - I have no idea now where I downloaded them from, been a long time since I found them.
This old topic may help.
