[?]: reTrial simatic software v5.4

[chama mulenga]

Hi,

I installed simatic s7 software on my toshiba laptop and it worked fine without going online because l dont have an MPI cable.
After l used it for 14 days the window started poping up saying no valid license keys.
l tried to uninstal the software and reinstal back still showing no valid license key.
We have a simatic PG for s7 which works okay.
is it possible to purchase the license keys from siemens since we have the license for the PG,l want to use the license keys on the toshiba laptop and buy the USB/MPI cable later on.

How can you deactivate the Trial License when the message appears indicating that the Trial License has expired, although the Floating License has been installed?
1. Remove trial key from C:\AX NF ZZ

2. Delete Trial folders (*ttis = 4PUPTPQWQattis (Step7), 4PUPsclpQattis (PLCSIM), ...) with 1 file 00000000000000000000.DLL (1280 bytes)
C:\WINDOWS\*ttis
C:\WINDOWS\system32\*ttis
