It has something to do with protected memory access which doesn't always get carried over in subroutines or sub-apps. I've had this issue with other software as well, where drag and drop from explorer to the app won't work if the app is run as admin. Go to Program files where you installed, make sure the 3 EXE files are not set to run as administrator. I will and I will get back to you with results.įound a problem with the UAC first run! That means there's a UAC access issue. Try installing the 32bit version and see if it will work.

Bottom line, your system may no longer support the handler being used. They are also trying to keep from overflowing a 32bit memory space, which is limited to 4gb normally, but can extend, with special programming, to 6gb. Windows has been pushing this kind of programming out, due to exploits in the 32 bit architecture that are rife with virus attacks. I would suspect (due to seeing the option appear in the tools menu) that they are using a component that is still tied to a 32bit handler. I had to update all my apps due to windows updates that broke functionality. I have updated those apps, I have reinstalled 7zip, and still found no solution to the problem. I uninstalled, then installed some other apps, then reinstalled. At the time I was using Windows 10 Home, I upgraded to pro workstation and it was still flawless.

When I installed the 64bit application, the problem was gone. I uninstalled and deleted all of it from my registry (all that I could find). The menu would display but nothing would work. However, after unistalling the 32bit, the problem showed up for the first time. However, I never experienced the issue when using both 32 and 64 bit versions together. Unfotunately, after some updates relating to security, I too experienced this issue.
