So I've been having trouble with my 7 zip on windows xp. I don't know what i did, but suddenly all of my normal folders,applications and files have started opening in 7 zip,even though their not zipped.It won't let my antivirus run. I've tried to uninstall 7 zip , but the add and remove program opens in 7 zip also,and shows some folders that are empty. Does anyone know how to help me fix this?
You can try uninstalling a program from command prompt.
Open up cmd product get name product where name="7 zip" call uninstall
You may need to replace 7 zip with the actual name of the 7 zip application
If it tries to open cmd with 7 zip try booting into DOS
To get cmd to not be opened with 7zip - http://www.sevenforums.com/tutorials/2630-default-programs-set-program-s-default-associations.html
You can change default program file association from within Control Panel >> Default Programs. I'd recommend checking there to see if 7zip has been selected for, what sounds like, the majority of the file associations. Microsoft documentation is available here.
