I've installed 7-Zip in XP and it creates a context-menu in Windows Explorer. But, in Windows 7 it doesn't. I don't know why. I tried it with administrator privileges, but nothing happened.

Version 7-Zip 9.20 (2010-11-18) for Windows .msi 64-bit x64 works well with context menu under Windows-7 – user77552 Apr 20 '11 at 19:38

It works fine on my installation.

Open 7-Zip and go to Tools > Options select the Plugins tab and select 7-Zip then click Options.

Make sure that they are ticked. If it isn't perhaps file this as a bug report, but it certainly works here.

I tried this, but it isn't working. – Abdulsattar Feb 4 '10 at 14:34
Must be a bug then - I would personally try unticking the boxes then apply / ok, and retick just to see, but Sorry - I cannot reproduce this. FYI, I am using version 4.65 – William Hilsum Feb 4 '10 at 15:20
Doesn't work for me either. I'm on 64-bit Windows 7. – Iain Feb 8 '10 at 23:22

The problem is that Windows 7 uses different context menus for 32-bit and 64-bit applications.

I fixed this problem by installing the 64-bit v9.10 beta version of 7-Zip. I then opened it as an administrator. I was then able to set 7-Zip file associations and apply the context menu.
