I am running ClawsMail 3.9.3 without issues on Windows 10, 64 bit. I recently tried to upgrade to the newest Clawsmail version, i.e. 3.15.0-1 but it does not start in windows 10. I tried both the 32 and 64 bit versions. I am sorry I don't have more information but there is no error. It just flickers a couple of times and does not start. Is there are log or debug I could provide?
You could try running claws-mail.exe with --debug flag, and then look for a file named "claws-win32.log" somewhere in your system's temporary folder (TEMP system variable). Also make sure that you have a clean install, by uninstalling Claws Mail and making sure that there is no "Claws Mail" (or the old install location, "GNU\Claws Mail") folder.
Created attachment 1746 [details] log I uninstalled the previous version. Checked that no folder is left in Program Files (x86) and reinstalled the new version.
Problem solved. It appears old versions of Claws Mail can not be upgraded directly to the newest version. All user data has to be deleted and then some of it can be copied back. Thanks.
Based on the log you provided, it seems like some of the old configuration files got corrupted and I was going to test a few scenarios when I'd get a bit of time. I am not aware of any change over the years that would make an older configuration incompatible, but it could be that there was (or still is?) some bug in the Windows port specifically that could cause this.
I have a similar problem.
