To be honest, I think a lot of Chinese translations of technical topics (or even not-technical topics) are quite poor, and little beyond a word-for-word substitution.

run -> 运行 ("to convey/process", the more common use of "run", of
                   'using your legs faster than walking' is obviously wrong)
time ->  时 ("hour", "during")
library -> 库 ("storage container", the more common use of "library" to mean "collection of books" obviously wrong).

Whereas
"執行階段程式庫"
meaning "the program/routine library of/in the execute stage" is quite a lot more fitting to what 'runtime library' actually means.

As I was saying, one needs to be vigilant about automated translations being 'not quite correct'. I suspect it is a much abused practice in China, so you see the same (mis-)usage over and over.

There are entire web sites devoted to poorly translated public signs in China and making fun of them. It is quite educational - one gets lazy and and accepts the occasional poor translation, but seeing similar but slightly different mistakes collected in a large quantity really makes one think.
