Question

I am using Inno Setup Key Generator (IKG). I successfully call ValidateSerialNumber

Valid := ValidateSerialNumber(ExpPath,RegName,'','','','',PrivKey,RegKey);

As long as I pass empty Strings for PrivKey and RegKey the function returns false as expected. As soon as I pass a value to PrivKey or RegKey I get the Error Message:

Access violation at address XXXXXXX in module ISID.dll. Read of Address XXXXXX.

Non-empty values for ExpPath or RegName do not have this effect.

The function is declared:

function ValidateSerialNumber(InnoKeyFile, User, Orgn, ProdCode, HDD, MAC, PrivateKey, 
Serial: String): Boolean;
external 'ValidateSerialNumber@files:ISID.dll stdcall';

What am I doing wrong?

Use are most probably using Unicode InnoSetup and that library counts with the ANSI version. I ‘ve found some manual for that library from the year 2004, when the InnoSetup wasn't Unicode yet, so try to use this ANSI import:

function ValidateSerialNumber(InnoKeyFile, User, Orgn, ProdCode, HDD, MAC, PrivateKey,
  Serial: AnsiString): Boolean;
  external 'ValidateSerialNumber@files:ISID.dll stdcall';
