I'm writing a manual, and needed to say something to the effect of "at
runtime", as in "Some program debugging can only be performed (or is more
efficient or accurate when performed) at runtime."
[(wiki)](https://en.wikipedia.org/wiki/Run_time_\(program_lifecycle_phase\))

I instinctively started typing "ランタイム時に" before realizing that I am
essentially saying "at runtime-time", or "at the time of runtime".

Is "ランタイム時" acceptable Japanese? What good alternatives are there in case I
don't want to or should not use it?

Is "ランタイム時" (runtime-time) acceptable?
ランタイム時に may not be that bad, but feels awkward as you guessed.

And Japanese ランタイム as a noun tends to mean "runtime **library** " (such as
JRE, .NET Framework) rather than "run time". For example,
"Javaランタイムをダウンロードしてインストールしてください".

The normal way to say "at runtime" in that context would be (プログラム)起動中に, 実行時に,
etc.
