Hi Max,
Here are the results from testing Release builds with different compilers:
Without PROTECT flag:
2 * X = 10
2 * X = 20
S is : Hello
S is : Massimo
<--- Finished in (0:01.40), exitcode: 3221225477 --->
With PROTECT flag:
2 * X = 10
2 * X = 20
S is : Hello
<--- Finished in (0:12.26), exitcode: 3221225477 --->
For protected version, the ProtectTest.log file looks like this:
* C:\upp-11979\out\MyApps\MSBT17x64.Protect\ProtectTest.exe 06.06.2018 09:27:24, user: tom
START DECRYPT
JMP NOT FOUND
START DECRYPT
JMP NOT FOUND
START DE-OBFUSCATE
JMP NOT FOUND
START OBFUSCATE
1. On protected version "S is : Massimo" did not print out.
2. Neither 32-bit nor 64-bit version printed out the encrypted data.
3. Please note the 12 second execution time on protected version. It started out fast but took quite a while to complete.
The behavior was exactly the same with MSVS15, MSVS15x64, MSVS17, MSVS17x64, MSBT17 and MSBT17x64.
I think obfuscation needs some tuning as well as encrypted data processing.
In addition to present-day compiler and U++ support, I'm especially pleased to see that the 64-bit variant is now emerging! Good work Max! 
Thanks and best regards,
Tom
Update: The 12 second long execution time was revealed in Task Manager to involve running "Windows Error Reporting"... I guess this is some sort of a crash and Windows 10 calls home immediately.
Update2: Data encryption/decryption works OK. The problem is entirely in obfuscation; When both obfuscated calls are commented out, encrypted data prints out OK and exit code becomes zero.
