We have a problem because the same type of USB protection key is being used for the protection of our own software. PerClass should check all available USB protection keys and select the right one.

Only perClass USB protection key present:
>> sdversion
perClass 4.6 (29-Jun-2015), Copyright (C) 2007-2015, PR Sys Design, All rights reserved
Customer: Kolektor, Samo Sela (KOLEK) Issued: 20-apr-2015
Toolbox with imaging,DB: Permanent license, updates until 2016.0420.
SDK: The license expires on 20-apr-2016.
Platform: ‘PCWIN64’, Installation directory: ‘C:\perClass_Pro_4.6\perclass’

Both USB protection keys present:
>> sdversion
Error checking out license: Wrong host for license (-4)
Please make sure the dongle is present.
Platform: ‘PCWIN64’, Installation directory: ‘C:\perClass_Pro_4.6\perclass’

Just to update everyone on the progress. We have first found that license files not using USB dongles work fine with additional dongles used by company of Samo.

Then, we prepared a fix for the USB issue. With this 4.6.1 build it is possible to use multiple USB hardware dongle keys without problems. The solution was tested by Samo and will appear in the next public release as a standard for all platforms and the SDK. In case anyone suffers the same multi-dongle problem, request the pre-release at
