if that doesn't work then you'll have to keep track of what files you copied and where you put them in the windows system folders. you'll have to write a custom script the copy those files into the appropriate places before you start your cd-based app.
same goes for registery entires. export the whole app register tree to file. you'll have to write a custom script to then copy the reg entries before the app starts up.
ok im gonna try all this but how do you keep it from installing anything? this isnt the only app i have seen do this. what im most interested in is trying to figure out how it leaves nothing in the host machine after removing the disk, thats what i want to figure out as i already thought of the dll/reg.entry thing
check this site out and look at the demos it leaves nothing in your machine they can do this with any app you like but like i said im not paying to do this with free applications http://www.navicula.com/Web/Documents/T ... formOV.asp
the webbased demos need a dload to run but they state they can put it on cd and nothing gets installed on the host machine
