Question on PC environment variable

Hi,

we are switching from NX 10 to NX 11 and the process is :

1) Delete NX 10 folder

2) Uninstall NX 10

3) Install NX 11

The UGII_BASE_DIR follow the new NX installation dir, but UGII_ROOT_DIR stay with the old NX 10.

Example :

UGII_BASE_DIR = C:\Siemens\NX11

UGII_ROOT_DIR = C:\Siemens\NX10\UGII\ 

I need to correct ?
