This is caused by the same configuration as issue 25166, so I'm closing this 
one as a duplicate.

[issue25162] Windows installation does not appear in list of installed applications

[Christian Ullrich]

New submission from Christian Ullrich:

The new Windows installer always places the uninstallation registry key into 
HKCU of the executing user. This is correct for a per-user installation, but 
when run with InstallAllUsers=1, the key should go into HKLM instead.

The "Programs and Features" list of installed applications is assembled from 
the HKLM and HKCU keys. In many cases, a system-wide installation will be 
performed by temporarily elevating the installer to a user account with 
administrator privileges on the local system. However, since Vista, the 
"Programs and Features" list is always run in the logged-on user's Explorer 
process, even when started by a different user (such as in an elevated command 
prompt). With the uninstallation key going into HKCU of some administrative 
account, the Python installation will not appear in this list, hence, cannot 
easily be removed.

Ceterum censeo: This bug would have been avoided by using MSI as the 
distribution package format.
