Hi all,

Having a problem while starting Calibre 8.48. After looking around on this forum and through Google on the net I found several possible solutions, but none worked. So I ran Calibre in debug mode. See the input between the star-lines below. I have Windows 7, Home Premium 64bit, as OS on an Intel based computer.
I have searched for msi files, removed them, reïnstalled Calibre and it started fine. Few days later same problem reappears. I have no more solutions, but really would like to continue using Calibre since it is a really fine program. I understand most of the functions I use intuitively.

Anyone?

Marc
