[New-bugs-announce] [issue43127] Unable to install Python 3.9.1 - Windows 10

[Adrian Lloyd]

New submission from Adrian Lloyd <adrian.e.d.lloyd at gmail.com>:

I get the following error when I try to install Python 3.9.1 on windows 10

0x80070659 The installation is forbidden by system policy.

The log gives more information:

[13A0:0FC0][2021-02-04T16:41:04]e000: Error 0x80070659: Failed to install MSI package.
[13A0:0FC0][2021-02-04T16:41:04]e000: Error 0x80070659: Failed to configure per-user MSI package.
[13A0:0FC0][2021-02-04T16:41:04]i319: Applied execute package: core_JustForMe, result: 0x80070659, restart: None
[13A0:0FC0][2021-02-04T16:41:04]e000: Error 0x80070659: Failed to execute MSI package.


I have looked on earlier posts and stack overflow and all suggest a registry fix to set DisableMSI = 0 in the registry, but according to windows documentation this doesn't apply to windows 10. Also the Installer folder which would contain this parameter doesn't exist.

Can you help?
