Hi Rowan, We already installed device pack 5 and even 6 but nothing changed!Thanks:) Amir

Hi,I found the directory where PI saves the device information. (See screenshot below)But I am not sure if there are some workarounds to edit some of these files to remove a "device already exists" issue!Regards,Amir 

Thanks Steve:) I'll try the option one and hope TAC can fix it!I know the option 2 but is not an option for my customer cause they have to pay additional support hours what they do not want to do after only two weeks of the new installation! Regards,...

Hi Mohanak, Our customers did not spend lot of money for a "Management Tool" which should be re-installed every two weeks!!!Sorry but for such a little issue I can not tell my customer: "We must install the whole thing again"!They spent about 2 weeks...
