I'm not sure this is strictly a windows probem because other applications work in the context menu (such as antivirus) The winrar knowledge base was of no use or I was not using the exact keyword for a proper solution. The problem I am experiencing is winrar won't work at all through the context menu and winzip will display on the taskbar but that is all. Both work if I double click and use its toolbar to extract. I have tried to reinstall and also tried reversing JV16 reg cleaner - but have no solution. I know there are some registry genius' here so I am posting this request for help. Thank you.
