Have a user whose app doesn't display a window. It's not on the taskbar nor the tray. All I'm getting is the "3CXPhone for Windows (32 bit) listed as a Background Process. Logged on as the admin, got it to list as an app which I could Bring to Front.. but after switching users twice now I cannot. Uninstall/reinstall was done first.. no dice. I tried gutting the files from c:\programdata and c:\program files (x86) between the next round of uninstall.. no dice. Found some registry.. still no dice. As a new user, it didn't show up on the admin console to add an extension et al. This user was on it for probably two weeks until letting me know it isn't working this morning. Ideas? 12.5.39117.982 Maybe some 12.5 SP1?.. seems to be more about SHA1 fun than this. Client is 50% softphone.. I could push SP1 tonight but it certainly means "updates" are coming for all.
