installing calibre

dan w. · 05-02-2012, 08:48 PM

i'm having difficulty installing calibre. during installation, a box opens and asks me to wait while installer finishes determining disk space requirements.It should take no more than five minutes but this step never ends. i'm forced to stop the
installation. another box opens and tells me set up has been interupted and my system has not been modified.

Define "never ends"- how long did you actually wait for it to complete? On slower machines, that step can take some time. Just let it sit and work, it should complete eventually.

This issue was looked into a while ago and a Microsoft employee got involved in trying to shorten or eliminate the process, since this is a function of the Microsoft installation software.

Unfortunately, he concluded there wasn't any way around it. It seems to be a function of large numbers of files in the installation package.

Yes, it is. That's why I wonder which Calibre version the OP is trying to install. Kovid mostly worked around the issue quite a while ago by putting all Python functions in a single ZIP file (pylib.zip) instead of having them in separate files.

That helped immensely.

Actually, if I remember correctly, the issue is more the types of files. The MS installer seems to be geared towards supporting executable, DLL and similar files really well, as in only needing to check the file checksum (stored somewhere in the file) to determine which files have changed and need to be updated. Calibre hals almost no such files, so the installer has to actually compare each pair of files completely to determine if that file needs to be updated.

Anyway, the bottom line still is to wait until that stage finishes
