Hi,
can anyone tell me which installer was used to create the (windows version) of the SumatraPDF-3.1.2-install.exe and why the prerelease version of the installer from https://www.sumatrapdfreader.org/prerelease.html isn’t able to extract it’s content when using the command line option /x?
Installer is custom written. It’s described in https://blog.kowalczyk.info/article/8nqb/writing-a-custom-installer-for-windows-software.html
Ok, thanks.
Is there a reason why the content extracting switch /x isn’t working for the current prerelease version?
E.g. I’m downloading the prerelease 32-bit installer from https://kjkpub.s3.amazonaws.com/sumatrapdf/prerel/SumatraPDF-prerelease-10740-install.exe
and put in it’s own folder:
D:\Users\oO0XX0Oo\Downloads\SumatraPDF extracted
open a dos box in this folder and use:
SumatraPDF-prerelease-10740-install.exe /x
Nothing happens…
When I do the same with the 32-bit release version from
https://www.sumatrapdfreader.org/dl/SumatraPDF-3.1.2-install.exe
it extracts it’s content just fine…
It may be a user limitation or directory rights bug
my experience
using /x alone seems there is an issue as I also saw no files,
however there seems to be a copy created today in my syswow64 directory (damn)
using /d “path\to\directory” /x I did get the contents extracted to where I expected them !
This is most likely bug introduced recently. I’ve opened https://github.com/sumatrapdfreader/sumatrapdf/issues/903 to track this.
@GitHubRulesOK
Using the /d switch works even with the prerelease installer 
Thanks!
