I am using 7-Zip 4.36 and would like to uninstall it. However, I do not see an uninstall function.
Also, I searched the help files and the term "uninstall" was not found.
Is it simply a matter of clicking on the Desktop icon and deleting it? If so, shouldn't the help files say this? Or the web site? Or something. I don't see uninstall information posted anywhere.
In case anybody else is interested in the same question:
In the following folder, there should be an executable called "uninstaller.exe":
Navigate to this executable, run it, and 7-Zip should be removed.
Hope this helps other people with the same question.

I've tried uninstalling 7-zip using both the windows control panel and following your instructions and running uninstaller.exe. I both cases, I get an error "error launching installer". Can you help me with this?
Thanks. Jim B.
Like most windows programs: go to the control panel and select Add/Remove Programs or Uninstall a program depending on your windows version.
More detailed instructions: In Windows, how do I uninstall programs?
I've tried the add/remove programs in the control panel and get the error I noted above. This seems to be more complicated then running an uninstaller app.
Perhaps you need to be running as an Admin level user?
Install over top.
Then see if the uninstall works?
Maybe something here:
Why do I get NSIS Error - NSIS
Have encountered the same trouble uninstalling 7-zip 9.22beta. It will uninstall. An NSIS error keeps occurring. I have Admin privileges so it doesn't seem to be a user issue. To date I have:
(1) tried to uninstall via Control Panel
(2) tried to uninstall using CCleaner
(3) downloaded 7z922.exe from 7-Zip site, re-installed, rebooted
(4) tried to uninstall via Control panel
(5) tried to uninstall from Uninstall.exe found in Programs(86)\7-Zip
(6) tried to uninstall using Revo Uninstaller Pro
See attached screen shots.
I am running out of ideas. How can I uninstall 7-zip (7-zip9.22beta)?
This program is preventing me from updating FF to 34.5. I tried to install FF 34 via exe and a 7-zip No permission error occurs. Any suggestions?
Note that Firefox installer uses 7-Zip SFX.
So you have 2 different programs:
2) 7-Zip SFX in Firefox installer.
You don't need to unistall 1) 7-Zip to install Firefox via 2).
You just have some problem when you call 2) 7-Zip SFX
Try some things:
1) call firefox installer with admin rights.
2) check temp folder.

You need archive with files.
copy /b 7zipInstall32.exe + a.7z a.exe
