Help: windows incompatibiliy prevents to safely run Emsisoft Internet Security in Other Emsisoft products Posted February 26, 2017 · Report reply I just found in several threads that " You do need the hotfix". Necessary to prevent Blue Screen Of Death or BSOD and other trouble. See the example below from a 'Emsisoft Employee'. So the 'hotfix' is necessary but now the hotfix does not install anymore.That makes the problem all the more urgent but nowhere a solution can be found. That would mean Emsisoft is no longer usable on Windows 7 installs. Therefore I am very curious to anyone his opinion / advice / help.
