HPFlashFix
Compiled Binary V1
This tool changes the due date of the native Adobe Flash application by binary patching the executable. This is necessary for applications like HP Solution Center in order to keep them working after Flash's hardcoded due date (after 12 January 2021).
The tool is built with C++ and Qt5.
The modified Flash binary turns the blocked HP Solution Center application

back into its original state.

DISCLAIMER: By setting the due date to infinity, you actively disable the kill-switch functionality of the native Flash application. This poses a potential security threat to your system.
