Just reinstalling 7-Zip (v.9.2) to a new system, and I cannot find the context-menu option in Explorer. In the 7-Zip options there is no plugins tab (as detailed in the documentation) to change this setting. Any idea how to get the option Explorer functionality working? I'm on Windows 7 64 bit.
First you need to start 7-zip "as administrator" the first time you run it to assign the context-menu option. Otherwise 7-zip does not have the right to change anything. (I don't know why 7-zip does not do this during install when it already has admin-rights but i always need to do this after installing 7-zip)
Then go to
Extra / Options. In the first tab (
System) you can choose what files you want 7-zip to associate with and in the second tab (
7-zip) you can choose the context-menu option (first checkbox).
You are probably using the 32bit version on a 64bit OS. Uninstall it and install the 64bit version. I have done this several times and that solution works for me.
If you're using the correct bitness of 7zip and have the correct settings set but it still doesn't work, then it may be that the wrong Explorer shell extension is enabled.
It turns out that even with 64bit 7zip installed you can end up with 32bit shell extension enabled, possibly a hangover from previous 32-bit install.
To fix this:
- Download and unzip ShellExView (x64 version) from the NirSoft website
- Run it and make sure
Show 32-bit Shell Extensionsis ticked
- Sort by
Descriptioncolumn and look for 7-Zip Shell Extension
If you find 7-zip Context Menu extension and the
7-zip32.dlland it is enabled, then you should right-click and
Disable selected items
Show 32-bit Shell Extensionsand find the 7-zip Context Menu extension again (filename should be
7-zip.dll) and enable it, this is the 64-bit one.
- Then close all explorer windows, click
Restart Explorerand then open a new folder window and right click on a zip file
- Assuming the 7-zip settings and associations are set up, the context menu should now show!
This was the only thing that worked for me. Even using the 64-bit version of 7-zip, and running the installer as admin, and running 7zip as admin & changing the settings, it still didn't work until I did this.
I ran into the same issue with missing 7=Zip context menus on a 64-bit system. Had first installed 32-bit and later 64-bit and kept trying to enable the context menus and they did not appear.
I resolved this from Windows Programs and Features by: 1) uninstalling the 32-bit version 2) selecting Repair on the 64-bit version
I had the same issue.
The 7z920.exe file contains the x86 and x64 installers -> I couldn't make it work.
I downloaded the 7z920.msi file which contains only the x64 installer and worked like a charm.
I received error "7-zip cannot load 7-zip.dll" when tried Rik's method.
My solution was to uninstall and then reinstall.
My laptop was running Windows 7 SP1 32bit so my 7-zip installer is 7.20 32 bit version.
Try a new version to install. I use this one and it works for me. http://www.7-zip.org/a/7z1602-extra.7z
