Xentry.exe(VeDoc calculator) is protected by WinLicense 2.4.6.0.
It can not run in Windows XP because it imports APIs from dwmapi.dll.

I played in Windows 7 with your valid license file regkey.dat:

1. Set a hardware execution breakpoint at 0147CB7B(where ModuleBase is 00400000);
2. F9, run. waiting for user32.MessageBoxEx(NULL, "This application has been registered to\r\nSkud1 - Private 2", "WinLicense", MB_ICONINFORMATION, 0);
3. Click Ok in MessageBox, then it should land on the BP;
4. At here, modify DWORD [0130A21D]=7CBDC03A;
5. Clear the BP, F9. You are free to go!

It's so simple, so easy to bypass the HWiD Check! Sad for Oreans.

For more technical details, please refer to my post years ago at tuts4you Themida 2.2.6.0, in which attached a WinLicense 2.2.6.0 example.
