Install old flash version 12 without annoying "your flash is too old" message

Hello, I'm looking for a freelancer to help me install an old version of Flash (version 12) without the annoying "your flash is too old" message. I'm using Windows and have administrator rights to install the software. I already have the old Flash version 12 installer, so the freelancer will only need to provide guidance on installation. This is a straightforward project and previous experience with Flash would be beneficial.
If this sounds like a project that fits your skill-set, then I look forward to hearing from you. Thank you for your time!
