Looking for RISA2D v2.1 for MS-DOS

Hi everyone,

I'm trying to track down an old structural engineering program — RISA2D version 2.1 that used to run on MS-DOS. I had a copy a long time ago, but unfortunately, I lost it and haven't been able to find it anywhere since.

I've searched across the internet, checked archive sites, old software forums — but no luck so far.

I'm really enthusiastic about vintage engineering software, especially ones that run on DOS. If anyone happens to have a copy of RISA2D v2.1, or knows where I might be able to find it, I'd be incredibly grateful.

Thanks in advance!
