#926: error: 12057 when installing OSGEO4W
---------------------+---------------------------
Reporter: ThierryL | Owner: osgeo4w-dev@…
Type: defect | Status: new
Priority: normal | Component: Installer
Version: | Keywords:
---------------------+---------------------------
Either through GUI or Command line (osgeo4w-setup.exe -q -k -r -A -s
https://download.osgeo.org/osgeo4w/v2/ -P proj).
Would not show mirror sites. Would not download. Finally found log that
showed that error 1205 appeared for every request.
Resolved on my PC (Windows 11 Pro build 10.0.2620) by
temporarily unchecking
Internet Options -> Advanced -> Security
_ Check for Publisher's certificate revocation
_ Check for server certificate revocation
_ Check for signatures on downloaded programs
_ Warn about certificate address mismatch
Did not investigate further.
Once working, these are the first few output lines from this command:
