Just quickly. Whilst I might have various old ColdFusion installers lying around, I am not a download service for complete strangers who didn't think to keep hold of their own software.
When it was one person once in a blue moon who needed help with this sort of thing, it was no problem. But I've had two complete strangers in the last 48hrs ask me for various CF installer files, so am making a policy decision that the answer is automatically "no" if you're thinking of asking me for a ColdFusion installer file. NB: to the two bods who asked for help... I'm not having a go at you: it was a reasonable question to ask.
I can only suggest you post a question on the Adobe ColdFusion forums, or contact Adobe, or ask on Twitter or something.
