so i installed 7zip on my laptop with default settings, and normally, if i were to right-click on a file with .zip extension (like the rawr installation download), it would appear in the context-sensitive menu. but it does not. when i look at the windows screen "open extension with a certain program by default", .zip does not appear there as well.
is there anything special i have to do in order for 7zip to appear in the context menu? i have windows 7 64bit home premium, on an acer aspire 5741G:
if it is anything worth, the PC default came with Mywinlocker, but i don't know what that is or if it has any effect on it.
