I tried installing texlive on a Windows 10 computer, and it failed with a cryptic error message, several times. Frustrated, I tried the option which only downloads and unpacks it.

Is there something I can do from here so I can continue the installation attempts without waiting every time multiple hours for new downloads? Or can I "install" it manually, for example by adding the now-existing latex.exe to the path or the registry?

  • I would first suggest you to download the ISO file once and make a copy of it. Have you followed TeX-Live site instructions for Windows? When does installation fail? What is the error you get? – ebosi Apr 11 '17 at 21:13
  • @ebo I got the installer from here: tug.org/texlive/acquire-netinstall.html. When I start it with administrator rights (virus scanner turned off), I get through the wizard (I leave all the options as they are preselected) and it starts the installation. The installation seems to work, counting through the packages, but takes several hours. When I come back to it later, it greets me with some noninformative error like "installation failed, try again" (always the same, I forgot the exact text). I have been through it 3-4 times, and it would take me half a day to reproduce the error. – rumtscho Apr 11 '17 at 21:24
  • The error message would be nice. It might also be an idea to use a better mirror. Where in the world are you? Exactly which of the two windows installers are you using? There is an exe and a zip. Thirdly, if you have the space, you can rsync the entire installation archive to local disk and installing from there. That should make reinstalls a lot faster. I tend to do the later and thus have a local archive for other pcs to install from. You can even place the tlnet stuff on a USB (though for Windows I'd still copy the contents of the USB to local disk before installing) – daleif Apr 11 '17 at 21:48
  • @daleif it is not about the mirror, it is my local network connection which makes it so slow. I used the .exe installer. How would rsync help? I do have all the files now, the "download option" only worked. What I don't know is how to do whatever else the installer would have done besides copying the files to disk. – rumtscho Apr 11 '17 at 21:58
  • Rsync takes the slow network out of the equation. The installer has to grap 3500 packages for your installation (depending on scheme) each time you attempt an install. Now imagine if those 3500 installation files were already on your computer. That is what rsync can do, create a local mirror (of a mirror that provides rsync access). You can run the rsync overnight. Look up rsync on Wikipedia, it us a super useful tool. – daleif Apr 11 '17 at 22:02
