Terry J. Reedy <tjre...@udel.edu> added the comment: "Other installers work without issue?" Is this a comment about other installers for other versions on your machine? Or a question about other people using the same binary on other machines?
Using the same python-3.7.0a4-amd64.exe binary, I successfully upgraded an existing 3.7.0a3 all-users installation in a custom C: directory on Win-10/64. If I read the log correctly, you tried a single user installation in the standard location. The first error indication I see in the log is this line: MSI (s) (BC:04) [20:15:48:208]: Note: 1: 2205 2: 3: Error 'Error 0x80070643' is a generic installation failure that can occur either during Windows update or 3rd party program installation. I searched and one of the top hits was https://www.drivereasy.com/knowledge/fix-error-0x80070643-on-windows/ You could try the 3 generic suggestions under 2) Fix the 0x80070643 error during a program installation (The first is restart your machine, if you have not already.) You could also run the system scan described in section '1)'. ---------- nosy: +terry.reedy _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32545> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
