The protected application works fine on the same computer where I did the protection. But when I copy it to another computer, I always get an error “CRYPTO-BOX not found” or “Protection DLL is missing or corrupted”.

If you receive a “CRYPTO-BOX not found” error please check the following:

  • Did you format the CRYPTO-BOX with your project settings using “CB Format” (or SmrxProg.exe)? Please refer to the AutoCrypt Application Note, chapter 4 for more details.
  • Is the CRYPTO-BOX connected and is the red LED light "on"? If not, please click here.

If you receive a “Protection DLL is missing or corrupted” message: 
During protection process, a file fmteos.dll (resp. fmteos64.dll for 64 bit applications) is generated in the same folder where AutoCrypt has stored your protected application. Please make sure to deliver this file together with your protected application.
