Need to overwrite ir50_32.dll with new version RRS feed

  • Question

  • Hi,

    I have an installation that requires to repalce existing version of codec ir50_32.dll in C:\Windows\System32 in Windows Vista with a later version.

    But the C:\Windows\System32 directory and the file are owned by TrustedInstaller and are protected resources included in windows protected resources scheme. I also understand that TrustedInstaller is not actually a user or a group but a service.

    The only way I have managed to get it to work is to change the owner on the advanced security settings from TrustedInstaller to an user of a local Administrator group and then replace the file.

    However, this solution is not suitable for an installation setup.

    There is an article on msdn http://windowssdk.msdn.microsoft.com/en-us/library/ms734601.aspx that describes the four supported ways to change windows resource protected (wrp) files or folders.

    Is there another way for my installation setup to replace ir50_32.dll file?

    Many thanks,

  • why do you need to change the system file > are you writing a application to use or replace functionality if so look at the MSDN Vista SDK groups
