launchwin.msi download is not working anymore (pynsist 1.12) #188

Closed eliabieri closed 5 years ago

eliabieri commented 5 years ago

pynsist version 1.12 downloads launchwin.msi from the following URL: https://bitbucket.org/vinay.sajip/pylauncher/downloads/launchwin.msi:

The file at this URL does no longer exist, thus the download fails with the following output:

Any ideas on where to get the launchwin.msi from now on? If anyone has an idea, I would then create a pull request. Thanks

Update: I tried to contact the owner of the bitbucket repo. Maybe he can reupload the file. https://bitbucket.org/vinay.sajip/pylauncher/issues/6/404-for-msi-installers

The 2.x series is the focus now, and so 1.12 is largely unsupported. If Vinay wants to put the msi file back up, that's great. But if not, I don't plan to spend effort figuring out alternative solutions.

And I wouldn't blame Vinay if he takes a similar attitude: the only remaining version of Python that doesn't ship with the py launcher on Windows is Python 2.7, which will reach the end of its extended life next year.

I understand. The problem is, that I have to ship an old python project which unfortunately cant me migrated to python3 yet. Is there a way to build an installer that circumvents downloading the PyLauncher? Thanks for the Help!

If you can find a copy of the msi somewhere else, you can locally patch the code that tries to download it:

https://github.com/takluyver/pynsist/blob/1.12/nsist/__init__.py#L249-L262

But I don't have a copy of it handy, and I don't know an obvious place to find one. You could download the source code and build it yourself, if you have a Windows machine handy and can install the necessary Visual Studio version on it.

I found the file in a windows installer package generated before. I uploaded the file here so others could copy that approach. launchwin.zip

takluyver commented 5 years ago

Vinay has put the files back up for download, so this should be working again now.
