On an older Windows 10 PC where an app suddenly stops opening, common causes are incompatible/old drivers or general app compatibility issues.
Try these steps in order:
- Run the Program Compatibility Troubleshooter
- Right‑click the H&R Block shortcut or EXE.
- Select Properties > Compatibility tab.
- Click Run compatibility troubleshooter and follow the wizard.
- Test the suggested settings and save them if the program opens.
- Update Windows and device drivers
Older or incompatible drivers can prevent apps from starting properly.
- Select Start > Settings > Update & security > Windows Update.
- Select Check online for updates from Microsoft Update.
- Install all available updates and restart.
- If the problem continues, update key drivers (video card, printer, mouse, keyboard) from each manufacturer’s website.
- If the app still behaves oddly If it opens but is glitchy (flickering, unresponsive, etc.), repeat the compatibility troubleshooter and confirm all drivers are current as above.
If none of these steps allow the H&R Block software to open, the specific tax program version may no longer be compatible with the current Windows 10 build and drivers on that PC; in that case, contact H&R Block support for version‑specific guidance.
