Could not load library '.../timescaledb-1.4.2.dll' unknown error 126

[rafaelcamposufsc]

I'm setting up the timescaledb in a Windows 10 with PostgreSQL 11.5 and timescabledb 1.4.2. But when I try to create the extension by running

CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;

I got the error

could not load library "[..]/PostgreSQL/11/lib/timescaledb-1.4.2.dll": unknown error 126

The dll file is there but for some reason it cannot be loaded. I've already trying with Postgre 10.10 and got the same issue.

Running into same issue. Piggybacking to see if someone knows the resolution to this problem.

check the dependency of the dll using http://dependencywalker.com/
I solved mine, it's the missing ssleay32.dll

@rafaelcamposufsc and @darophi can you confirm that the missing dll as pointed out by @resoftw fixes this issue for you as well or are you still seeing the issue?

[cristihcd]

see #1398 (comment)

[cevian]

@rafaelcamposufsc did the suggestion in #1398 solve your issue?

[mkindahl]

As given in #1613 and #1398 missing to install libraries will cause this issue, in these issues it was missing ssleay32.dll and libeay32.dll. Closing issue as duplicate of #1613 and #1398. Please reopen if that is not the case.
