There should be no problems with v1.5 and winxp sp2...
It could be what is mentioned in Post#15 by Zygalski,
so this means that maybe a file is missing in your winxp system
or your system is in a bit of mess as said, but this does
not mean you need to format & re-install your OS. Yet.
Let's start by checking if file AUTOEXEC.NT mentioned by
CD/DVDgen is where it should be, press 'start' on desktop
in menu select & click 'Search' make a file search with
AUTOEXEC.NT
Search results should be the following;
(i). autoexec.nt = located in C:\Windows\Repair
(ii). AUTOEXEC.NT = located in C:\WINDOWS\SYSTEM32
If both files (i) & (ii) are found your system is ok. Now....
1. If file (ii) is missing we have found the problem, all you need to do is...
(a1) COPY 'autoexec.nt' file located in C:\Windows\Repair
(b1) PASTE file into C:\WINDOWS\SYSTEM32
(c1) Run CD/DVD-Rom gen v1.5. All should be fine now.
OR
2. If both files (i) & (ii) are found your system is ok, but...
(a2) 'CD/DVD-Rom gen v1.5' you have is corrupted, try dl'in app from
http://members.cox.net/candrid2/files/cddvdgen.rar
or
http://home.versatel.nl/joeriroels/Download/cdgen_15.rar
(b2) one / or both (i) & (ii) files are corrupted (maybe recent virus?).
(c2) Your system is in a mess, and you need to blow it up. Post 15#.
hope this helps & good luck.
