Hi Johan,
Tim had the same problem, and so the solution _might_ be the same.
You can test;
a) open a command prompt window
b) type
SET OPENSSL_CONF=c:\temp\a.cnf
c) leave the command prompt window open for the test
d) create an empty text file, c:\temp\a.cnf
e) repeat the get-certificate test.
Cheers
Bruce
