Can't reverse to Daemon 3.47

[2FaT4u]

I have a problem here, i had daemon tools 4 and uninstalled it carrectly. So now i wanna install the good old Daemon 3.47 and then it gives me and error that says that a need to change driver name, or reboot my computer.

Maybe i chould change the buss drive name? or what should i do.

Btw, i changed name on the sys fil that the mentioned maybe was wrong.

First of all ensure sptd.sys is removed, check thread about how to remove v4 in common problems and solutions forum.
Regarding the driver name error check thread about error 25002 in common problems and solutions forum, reboot after the procedure - then re-install.
