replacing unused computer

[Maciej]

Gentlemen,

I've tried to remove nXt from the computer I am about to reinstall.

That is what appears on the screen:

Cannot open DCL input file: comm_replace_computer.dcl (appl: comm) dcl: c:\program files\accurender nxt\RPS_Bin\..\RPS_Support\appl\comm\dcl\comm_replace_computer.dcl

(Error occurred in ..\rps\dlg_dcl.cpp line: 125)

Current dialog: 'Licensing nXtRender for AutoCAD V: MD02w 1.0' ('comm_license' button sid: button-24: bskip: 0 : LB: Replace Unused Computer)
command: dc_license_dlg_online("comm_license", "replace")

#Date: '03/29/2014 14:43:41 Środkowoeuropejski czas stand.'
#License: 'XAMG07106I'
#Computer: 'NTT'
#Product: 'nXtRender for AutoCAD'
#Version: 'MD02w 1.0'

So, Is there anything I should do before re-installing Win7, Acad and nXt?  Computer name (NTT) will be exactly the same after re-installing Win7, so will be users name (mx2)

Thx in advance for any answear..
