Hm. I don't understand the question. Each device comes with its own driver. Resp. can be downloaded from Epson. The question would be why would I want an old driver? Without knowing, however, I maintain it can't work.
If you are referring to the Silverfast from the V750, it certainly won't work. But there is a relatively cheap upgrade available. I did it from Epson 4990 to V850.
With the Epson scan programme that comes with it, you can also achieve very good results. But I find Silverfast better.
If you have any further questions, please do not hesitate to contact me.

Normally the software is included. (or downloadable from Epson) I need Epson Scan. I run the 750 and the 850, in the drivers the 750 is recognised under the 850 software and works fine. You can also "run" scanners with VueScan. This is especially useful with old devices.

Unfortunately I can't give you an answer because I haven't tried it, but you should be able to read more about it on the Epson site.
Kind regards
