Hi,
Trying to re-install fsx in D: but it redirect me automatically to C:

and continue the installation without the normal slide image.
After inserting disc 2, it continues the installation but arrived at the Direct X & SDK path. It stops and get a message ' installgamehelper.dll cannot be found'
Why does it do that?
Please help me to solve this problem

Thanks in advance.
Regards,
Patrick.
