Has anyone been unable to open Sibelius First because a Bad Image Error report comes up - No. 0xc0000020. It says to uninstall and then install again which works the 1st time I open it after doing that but not thereafter - more Bad Image reports.
Which version number of Sibelius First?
Which version of Windows are you using?
If it is Windows 10, also give the version number (e.g. 1607 or 1703).
Which brand of anti-virus are you using?

Sibelius 8.6/7.5.1/7.1.3/6.2/5.2.5, PhotoScore Ult 8.0.4, Dolet 6.6 for Sibelius, Windows 10 64-bit 16GB. Desktop no-name, Microsoft Surface Book.
You are the fourth or fifth person in the last month who has reported that problem with that exact combination of Windows 10 and McAfee anti-virus. I suspect a McAfee problem.
If you disable the anti-virus, does the problem stop happening?
Are you sure that you are running the latest update of the McAfee programs?

> McAfee up to date. Disabling McAfee makes no difference.
Disable McAfee. Reinstall Sibelius. Keep McAfee disabled. Are you then able to launch Sibelius and not have this error occur? And close and re-launch Sibelius repeatedly?

I suspect that the issue might be related to which anti-virus was in use the LAST time that you used the application: i.e. the time before when Sibelius gets an error when opening.
