Ok when you take your cd in your drive "e", Start the installation, pay close attention in the installation when a page comes up saying something like "destination" or where do you want to install the softwrae. From this point, there should be a field where the navigation to where the software will be installed is written out:

For example: A page from the installtion part of the cd may look like this

PLEASE STATE WHERE YOU WANT THE SOFTWARE INSTALLED

(below these words a box on the bottom and in it looks like this below:)

D:\PROGRAMFILES\YOURTITLESOFTWARE

From there you can take your mouse and erase what drive letter (like D for example) and type in the letter of the drive you are using which is E.

so in that field, you would write in that box: E:\PROGRAMFILES\YOURTITLESOFTWARE

Now if this does not work let me know because the next step would be to change the drive letter assignments which is very lengthy to write.

Let me know how that worked for you but this should work ok?

Good Luck
