Need to tile entire house (ceramic tile) . Right now there is commerial 12×12 laminate put down with the black adhesive. Cant remember the name of that type of tile tile.
How do I get the adhesive up to ensure the thinset will stick?

What do you mean by "laminate" -- some sort of plastic tile, or laminated wood tiles?
How old is this tile?
Tile older than maybe 35 years old may have been put down with an asbestos-containing adhesive. (And tile some years earlier than that may itself contain asbestos.) How serious a hazard this is really is hard to say, but if you're doing this commercially (vs as a home owner) then you definitely need to find out the asbestos content and follow all rules for removal and disposal.
As to the adhesive itself, I believe that in some cases it can be left in place and thinset put over it, but in our two small bathrooms I used paint remover the first time and heat the second time to remove the stuff. Likely neither option is particularly attractive for a whole-house job.
Good call
Cut glue or cut back glue was used well into the 80's before the switch to latex bases really took hold. the fact that he has 12x12 tiles indicates that there is little likelyhood that they contain asbestos. Most of the asbestos containing tile was in the 8x8 size, but we still send out larger tiles to be tested.
I would likely leave the glue in place and add a layer of 1/4" tile backer board. Then he would have the correct supstrate for ceramic tile and have encapsulated and asbestos in the glue without any undue exposure.
. The tile I was thinking of is called VCT. 1200 ft home with VCT all through it. Glue is black cut back. What about Ditra? Would that work ? or is that just postponing the fact that the VCT and adhesive still need to come up?
VCT is vinyl composition tile. It contains no asbestos.
Is this over a concrete slab, or wood underlament floor?
Removing Adhesive
I used Sentianal 747 Plus Adhesive Remover, and a long handled scraper. I got the adhesive remover at Menards. I just used it yesterday for similar problem on concrete. A few areas needed 2 applications, but most of it came up in 1. Sawdust works well to clean up.
