I am using InstallShield to create the setup for my application. However, I want to ask if there is a way to decrypt my dlls and folders that comes alongside the .exe file? I don't want anyone to access my dlls and setup folders.

    Once a user installed your software the DLL's needs to be stored decrypted on the users local filesystem anyway. Why bother encrypting them in the MSI? – rene Jan 20 '19 at 12:59
  • to avoid anyone to change in it in a way or another , and I want to set password for folders that alongside in exe to avoid anyone to play/access files in it – Omar Abo Elsoud Jan 20 '19 at 13:05

    Sign your MSI: https://stackoverflow.com/questions/1652301/how-to-sign-installation-files-of-a-visual-studio-msi – rene Jan 20 '19 at 13:08
  • And you can't deny access to files to a user who installed it and/or needs the files to execute your program. Security is bound to a user, not to a process. – rene Jan 20 '19 at 13:10
  • see also the blogs on OldNewThing with these titles: [*It rather involved being on the other side of this airtight hatchway*](https://www.google.com/search?q=%22It+rather+involved+being+on+the+other+side+of+this+airtight+hatchway%22+SITE%3Ablogs.msdn.microsoft.com) – rene Jan 20 '19 at 13:17
  • Are these assemblies or Win32 files or COM files or what? [I just added this answer yesterday for how to embed assemblies in a single file](https://stackoverflow.com/a/54267966/129130). To protect such an assembly, you might need obfuscation that I am not up to speed on. – Stein Åsmul Jan 20 '19 at 14:42
