Hey guys, hopefully somebody here can help me. I am trying to create a rebuilt, updated .NET Framework 4.5 installer ***exactly as the original.*** I have managed to split the SFX from the original installer, integrate the updates and rebuild everything again but the only problem is the setup.exe checking for digital signatures (of the updated .mzz and *.msi files) that causes it to fail If anybody knows how to remove the signature check from the setup files I would greatly appreciate your help (I think its either Setup.exe or SetupEngine.dll need to be modded) BTW I don't know if this clue helps, but I notice that I can use the modded installer to "Uninstall" the Framework if it is already installed, the setup verification of the modded msi and mzz files passes Here is a link to the original installer http://www.microsoft.com/en-us/download/details.aspx?id=30653
