Re:

opening a NEW file of your own (e.g., I2.IN.HPSPOOL).
(Because your post said foptions were 0) Sounds like I was right.
You can't FOPEN an existing #I file.

There are at least THREE reasons you can get an FSERR 45.
1) you aren't in privmode
... most common
2) you didn't supply the matching negative filecode
... fairly common
3) you didn't supply the correct priv level via HPFOPEN
... nearly unknown to users :)

Use flabelinfo?
Ok ... so you really want to open a #I file for reading.
You have to call HPFOPEN, foptions = 0, aoptions = %300 (usually),
and specify the correct privlevel.
Here's an example showing the priv level of a typical #I file...
:listfile i2.in.hpspool,-3

So, you specify the HPFOPEN option 38 with a value of 2.
This is one of the cases where FOPEN can't be used successfully.
