[issue28781] On Installation of 3.5 Python get error message

[Steve Dower]

Steve Dower added the comment:

> installed 3.4 afterwards

Did you mean 3.5 here? If you're going to change versions, I'd at least suggest 
grabbing the 3.6 beta - it's *much* better than 3.4, and we've had very little 
trouble with the most recent version (RC is coming in a week or two).

Mark Harris added the comment:

No worries Steve, I've managed to fix it.

I uninstalled, went through regedit & removed all mentions of python. I then 
installed python 2.7, installed 3.4 afterwards, uninstalled python 2.7 and for 
some reason that worked, it is working correctly now!

Thanks for all your help,

Mark

Mark Harris added the comment:

Hi All,

Just wanted to check if there is any progress on the below? I understand it's a 
bit of a mess, however I use python in my day job(this is on my work pc) so any 
help getting it sorted would be great.

Thanks again,

Mark

[Steve Dower]

Steve Dower added the comment:

That's only the most recent set, and all it shows is that the per-user install 
didn't help.

Do you have the earlier sets of install logs for the per-user install and 
uninstall? I'd like to see why those didn't have the effect I expected.

[issue28781] On Installation of 3.5 Python get error message

[Mark Harris]

Mark Harris added the comment:

I installed python just for my user, attempted to run python just out of 
interest in the command line and again the same error appeared (missing 
python35.dll).

I uninstalled that then reinstalled for all users, and again during 
installation the message missing python35.dll appeared. 

Any other suggestions? Thanks for the help so far.

[issue28781] On Installation of 3.5 Python get error message

[Steve Dower]

Steve Dower added the comment:

Looking at those logs, it seems like we think the per-user packages are already 
installed. When you go to do an all-users install, it "removes" the per-user 
packages, but passes in the same options as it does for the all user packages.

Under the hood, these packages are actually identical, and we run them with 
different options depending on what sort of install you're doing. One of these 
options is the install directory. When we install the all users package to 
C:\Program Files, then remove the per user package from C:\Program Files, it's 
actually just removing itself immediately.

I *think* the best way to deal with this, given that running the msiexec 
commands didn't work, is to do a Just for Me install first, and then uninstall 
that and do the All Users install.

You can see in the main log file lines like this:

[1B20:05AC][2016-11-28T11:44:53]i301: Applying execute package: core_AllUsers, 
action: Install, path: C:\ProgramData\Package 
Cache\{EB0611B2-7F10-4D97-BCF2-DCAAB1199498}v3.5.2150.0\core.msi, arguments: '

[1064:274C][2016-11-28T11:44:59]i319: Applied execute package: core_JustForMe, 
result: 0x0, restart: None

Notice that the package names (core_AllUsers, core_JustForMe) are different, 
but TARGETDIR is the same. It also seems that the packages are always ordered 
all users first - possibly this issue could be avoided if we did not interleave 
the packages, though you'd likely still not get a working install at the end.

Eryk Sun added the comment:

Please zip and upload the installation logs since your most recent attempt in 
msg281849. They might help to figure out why it's doing a per-user uninstall 
that removes python35.dll.

[issue28781] On Installation of 3.5 Python get error message

[Mark Harris]

Mark Harris added the comment:

Thanks for the advice, I downloaded the Python35.dll in the file located here 
https://www.python.org/downloads/release/python-352/ which was called "Windows 
x86 embeddable zip file". With this file when I enter python.exe the program 
crashes.

I tried Windows x86-64 embeddable zip file however it said it was the wrong 
version. Am I using the wrong link? 

I tried repairing python and the installation processes deletes the 
python35.dll file in the directory and then the end of the installation says 
the same error as befere (python35.dll being missing etc.)

Sorry about all the posts, would really like to get python working again!

[Eryk Sun]

Eryk Sun added the comment:

No, Python 3.5 is the first version to always place the interpreter DLL in the 
installation directory, beside python.exe. Installing for all users does not 
place python35.dll in "%SystemRoot%\System32".

You could also download the embeded build which ships with python35.dll to put 
it in the folder you installed python to alongside python.exe.

Decorater added the comment:

Normally when you install python systemwide it installs python35.dll in 
%SystemDrive%\Windows\System32\. Try looking there maybe you can use regsvr to 
register python35.dll in the registry or find where python.exe is and copy 
python35.dll to there.

[issue28781] On Installation of 3.5 Python get error message

[Mark Harris]

Mark Harris added the comment:

Hi Steve,

I did as you suggested, removed following add remove programs, removed every 
instance of python I could find(folders etc.), cleared out the temp folder.

Then I ran the commands you suggested(it couldn't find any of the registry keys 
this time), reinstalled from scratch and again when it was coming to the end of 
the installation the same message as before appeared "The program can't start 
because python35.dll is missing from your computer. Try reinstalling the 
program to fix this problem".

I'm still getting the same issue. I was installing for all users, was that part 
of the problem?

Thanks,

Mark

Steve Dower added the comment:

I was hoping that Repair wouldn't be an option after doing that cleaning. Maybe 
try uninstalling through Programs and Features, then run those commands again, 
go into the places you installed it and delete the files, and then run a fresh 
install.

If you still get the Modify/Repair/Uninstall page when you run the installer, 
keep doing Uninstall until you get back to the Install/Customize page.

[issue28781] On Installation of 3.5 Python get error message

[Mark Harris]

Mark Harris added the comment:

Hi Steve,

Thanks looking into this for me. I tried the below and ran the lines in cmd 
with admin privileges. Then I tried running repair again. I'm afraid when I 
type python in the command prompt it has the same message as before about 
missing python35.dll. 

I know you said that not all the commands would work, however when I ran "reg 
delete HKLM\Software\Python\PythonCore\3.5-32\InstalledFeatures /f /reg:32" it 
couldn't find the file. I don't know if that helps at all.

If you wanted to know how I caused this issue, I was having problems getting 
pip to work, so tried re-installing a few times(clicking generic user a few 
times in installation), into various locations, thinking it was something to do 
with the PATH. It didn't seem to be updating the path in the installation.

Hence why it's a bit of a mess! Any suggestions on further cleaning I could do?

Thanks again for all your help on this.

Steve Dower added the comment:

Oh wow, I've never seen anything like this before. It looks like it's really 
confused about whether you've installed for all users or not.

I wish I knew how you got into this state, because I'd like to be able to 
prevent it. I guess it's related to the current issue where the install 
registration is always for the current user, even when the install is for all 
users, but it still shouldn't be possible to get into this state.

As far as cleaning up goes, try running the following commands from an elevated 
command prompt and then doing another install/repair. (Some of them may fail, 
which is okay.)

msiexec /quiet /x {EB0611B2-7F10-4D97-BCF2-DCAAB1199498}

Thanks for the message. I've tried using repair, reinstalling etc to no effect. 
I've ziped up the files I could find starting with Python in the temp file you

Steve Dower added the comment:

Do you see a "Repair" option when running the installer again?

If not, open Programs and Features and find Python there, double-click it and 
select "Repair".

Otherwise, you should have a set of log files in your %TEMP% directory (sort by 
date and they all start with "Python"). If you can bundle those up and attach 
them to this issue, I can take a closer look.

[issue28781] On Installation of 3.5 Python get error message

[Mark Harris]

New submission from Mark Harris:

While I am installing python when it gets towards the end of the installation 
the message appears "The program can't start because python35.dll is missing 
from your computer. Try reinstalling the program to fix this problem".

Apart from this message the installation finishes successfully. When I type 
python into the command prompt the message appears again. 

I've tried as suggested installing again, it was installing to my local file 
C:\Users\myusername\AppData\Local\Programs\Python\Python35-32 so I thought it 
might be something to do with the path not being setting up correctly and have 
tried several locations.

The installer doesn't seem to be adding the PATH file on installation to the 
system as well.

This all started because pip stopped working and I was trying to re-install to 
resolve the problem. Any suggestions on a fix?

Thanks,

Mark
