Found Struc Plus 2000 Version 6. I think is the last version created and sold because the programmer site is dead and I didn\’t see any reference about a new version. If someone owns a new version please share.
The setup expands in directory C:sp2000 and creates a useless shortcut (for old versions of Autocad, maybe for LT according to the text).
The directory includes three menu files sp2000, sp2004, sp2006. No difference between files and only sp2006 attached to my upload.
The only protected file is sp2000.fas and after disassembling it and checking other issues this is my conclusion.
In the process of setup the installer create a text file named filelist.exe. The file contains the HD serial number but you can change it to any 8 digit. The serial number is created when formatting the HD and is an 8 digit (hexadecimal) as 4842-f20b. In the included filelist.exe I changed the number to 0000-0000.
Loading the application for the first time, in the authorization dialog you will see a serial number as A24100864ALL16H. The first A is not important and the last ALL16H the same.
According to the AutoCAD version the end of the string maybe 15H, 16H but again it\’s not important.
The application write a value in the registry and after input of the authorization serial it will write another value and the soft is authorized. Deleting those values will unauthorize the application.
Instructions for installing and authorizing.
Unrar the archive and copy the directory sp2000 to C:.
Open AutoCAD and using Tools/Options add in Support File Search Path the sp2000 directory.
Using the MENULOAD command loads the sp2006.mnu and after restarting AutoCAD continues to authorizing process. For authorizing use the formula:
Authorization Number = (X + 5535)/32 where
X = your application key without the leading A and the ALLxxH at the end.
Use the integer part of the result as Authorization number. For the 0000-0000 in filelist.exe the number is 173.
Checked in AutoCAD 2006 and AutoCAD 2011 and no difference. The version check in sp2000.fas is not rel
