Hi, 

I have a STEP 7 Safety advanced combo licence key in my laptop for some reason i transferred that licence to my pendrive and now i'm trying to transfer back to the original laptop, but i'm having error as "Licence key STEP 7 Advanced combo could not be transferred because it is inactive".  Is there any solution to transfer the licence back to my laptop?

Hello Dineshdeva!

When you are transferring the license, is TIA Portal open? If so, close all TIA software and check that in the ALM the icon next to the license is now a black line. This symbol indicates that the license is not in use and can be transferred.

Good luck!

Yes, That's really good information, but i realised when I had that error. now I need some solutions to activate it back. 

 In that case, you should create a Support Request so they can recover the license

Create a Support Request

use another flash drive. It worked for me..
