When installing the ECUHELP KT200II ECU Programmer, if got this error “WinLicense An internal Exception Occurred”, please follow the following 2 optional solution. 

Image 1 shows the error:


Possible reason:
The issue was entirely caused by Windows DEP (Data Execution Prevention) blocking the software's memory addresses.

Solution: 
Instead of formatting, adding the KT200 II executable to the DEP exception list fixes the problem immediately. You can suggest this workaround to other users facing the same issue:

Solution Steps:
Open Advanced System Settings in Windows.

Under the Advanced tab, click Settings in the Performance section.

Go to the Data Execution Prevention (DEP) tab.

Select "Turn on DEP for all programs and services except those I select:".

Click Add, select the KT200 II main .exe file, and apply the changes.

Restart the software.

Another user's successfull experience for sharing: 
Working solution:
Solution 1:
Longer but better, it consists in resetting Windows and performing a clean installation since some settings and permissions derived from old software can create interference (security permissions)

Solution 2:
Quick solution is to disable 2 Windows security settings (or whitelist the program) I attach a photo. 
Disable (this setting disables control over any software installed on your PC).
Or you can combine kt200ii.exe and D FOX.exe in this list.
