Using the same software installation from 2 Xp different installation

[sonnet]

Hi guys I want ask if can do this (and eventually how..):

I have a pc with a dualboot operanting system:

1)on partition C, I have installed Xp (with no application )

2)on partition D I have installed the application that I use with XP

3)On partition E I have installed Ubuntu.

Now within Ubuntu I have created a virtual machine with Windows Xp installed,so that I have not to reboot to use an application that is Windows ONLY.

Now what I want to ask is: can I launch from the Xp installed on the virtual machine, the applications installed on Partition D?

I know that's normally is not possible as when an application is installed under xp the register keys are modified, but if I export the register key from the native XP installation and import to the XP installed in the virtual Machine?If this is going to work ,which keys I have exactly to export/import?

It depends on the application. Registry keys may not be the only thing you have to deal with. A lot of times there are DLL/OCX files that are also registered and required for the application to properly function. 99 times out of 100 it'll be more trouble than it's worth instead of just doing a second install of the applications. It's only drive space and drives are cheap now days.
