I rebooted and deleted the preview folder and it crashed again. The error message suggests I re-install.

Will this really help?

Thanks

I have the same or a higher version (which the download below discovered:

"Same or higher version of .NET Framework 4.5 has already been installed on this computer."

Anthony: can we have another solution? It is really bothersome to repeat your work OR to keep saving large websites to avoid repeating work.

Thanks

Hello Akram Najjar,

What Windows version are you using?

Can you please send me a screenshot of the crash?

Many thanks!
