Solution to CS3 not installing.

I figured out why Photoshop wouldn't install.

Apparently if you have a 64 bit processor with DEP (Data Execution Prevention) turned on the install will fail.

You will need to change your boot.ini file to have this setting:

/NoExecute=AlwaysOff

Here is the KB article on it:

Once I disabled DEP Photoshop installed with no problems.
