I had been using Boris FX on an older PC, and recently got a new one with Vista 64 bit. I tried installing Boris FX, and it installed, but does not show up in Adobe Premiere Pro 1.5. I spoke with Boris support, and they said to download the update. I did that, but it still does not show up. If I run Boris keyframer itself, that works, but I can't get it to appear in my effects in Adobe Premiere.
Hmmm ... I highly doubt that you'll be able to run any current version of Boris FX software in Premiere Pro 1.5, I'm not even sure what version we have that is compatible with that (quite old) version of Premiere ... can you please tell me what is the EXACT version of Boris FX that you are trying to use?
