[issue34528] Windows installer: Failed to run untrusted mode.

We're totally okay with you using a different installer if you want. We know 
and trust Anaconda, and while they do things differently, if that model works 
for you then it'll be fine.

Python 3.7 shouldn't need any registry settings or environment variables to 
operate correctly for the most part - I fixed those dependencies in 3.6. You 
may need to "python -m pip install --force pip" after copying it though, if you 
want to use the plain "pip" command ("python -m pip" will work). You also won't 
get the py.exe launcher unless you copy that from C:\Windows.

Good luck!

[issue34528] Windows installer: Failed to run untrusted mode.

Knowing the IT department, I will receive a nice letter saying that they don't 
care because it is not an approved software and that I could use Java for my 
development needs. I wanted to develop some interesting tools in python that 
could be used by a lot of colleagues to force their hand in approving it in a 
quicker way, else it will be like they have done for php and in 5 years they 
will finnally approve the use of python 2.7 (without pip to install non 
approved libraries) as a standard tool :(

If I want the latest and greatest Python environment, it would be easier for me 
to copy a working installation from my computer and update the registry and 
environment variables like the installer should do. For that purpose, do you 
have somewhere the list of registry keys and environment variables to 
insert/update?

In the meantime I have found a 'workaround': Install Anaconda. I will not have 
python 3.7, but 3.6.3 is better than nothing :/ But still a pity to install 
600MB of cruft for the 30MB of Python goodies :)

Unfortunately, I don't have any better suggestion than trying to get your 
company policy changed :(

The "clean room" feature of our installer is not configurable (and also not in 
our code, so we can't change it without going through the upstream project). 
You will likely have similar trouble with any other installer that uses the 
same project, which includes many of Microsoft's programs - if there is an 
exception for Microsoft signed code, perhaps you could request an exception for 
PSF signed code?

If you have more information about the specific technical configuration that 
prevents this, then I may be able to follow up with people to find other ideas.

[issue34528] Windows installer: Failed to run untrusted mode.

New submission from Cabu :

At work, we are using Windows 7 Enterprise. I have local admin rights on a 
separate account.

When trying to install Python 3.6.3 or 3.7.0 for amd64, the installer stop 
after a couple of seconds without any message/popup. But, I have found the 
attched log in a temp folder.

It seems that the installer try to run a copy of itself in a folder where even 
the local admin can't run executables by company policy.

I didn't find any issue with the same error code in the tracker.
