Trying to install python but it keeps cancelling my installation


the progress bar fills up until a certain point, where it starts decreasing again automatically until this error message appears: “the user cancelled the installation” (i didn´t)

One could debate whether it is the best solution, but I’d try installing anaconda instead. Download Anaconda Distribution | Anaconda (It’s a way to run & manage Python)

You will have a set of log files in your %TEMP% directory, all starting with “python”. One of these is likely to have the cause of the issue in it - you can either search for it yourself or upload them all somewhere we can look at them.

If you already have an earlier version installed, you could try repairing it (run its original installer again, or find it in Installed Apps and select “Modify”), or uninstalling it. That tends to resolve this kind of issue. If you don’t have an earlier version installed, it’s probably going to be due to your system configuration - the log files will show that.

I tried installing again yesterday, so here are the archives: Upload files for free - Python 3.13.3 (64-bit)_20250429154522_000_core_JustForMe.zip - ufile.io

Unfortunately, that site keeps giving me a corrupted archive.

Perhaps you could upload to https://gist.github.com?

There are too many of these files so i only uploaded the 19 most recent ones

Thanks, I see the error (in the line below from the doc MSI), but I’ve never seen this before and have no idea what it means.

MSI (s) (50:F8) [15:46:05:264]: SECUREREPAIR: SecureRepair Failed. Error code: 3662BA448

There are a number of access denied-like error codes in your logs, which I think usually aren’t there. What anti-virus are you running? And can you update/disable it while you install Python? It may be triggering on something in one of the documentation files.

Alternatively, do a custom install and disable docs.

I disabled Panda Dome (my antivirus) and did a custom installation without installing documentation and it worked. I checked on the terminal if i had python right after and also tried to run a python file, everything is working like normal again.

Thank you so much.
