Hi Guys, do you have any ideas about this? Andy, was the latest native XEmacs distributed by netinstaller built with the portable dumper option? Looks like bad old ... File: xemacs-faq.info, Node: Q6.4.1, Next: Q6.4.2, Prev: Q6.3.4, Up: MS Windows 6.3: Troubleshooting ==================== Q6.4.1 XEmacs won't start on Windows. ------------------------------------- XEmacs relies on a process called "dumping" to generate a working executable. Under MS-Windows this process effectively fixes the memory addresses of information in the executable. When XEmacs starts up it tries to reserve these memory addresses so that the dumping process can be reversed - putting the information back at the correct addresses. Unfortunately some .DLLs (for instance the soundblaster driver) occupy memory addresses that can conflict with those needed by the dumped XEmacs executable. In this instance XEmacs will fail to start without any explanation. Note that this is extremely machine specific. 21.1.10 includes a fix for this that makes more intelligent guesses about which memory addresses will be free, and this should cure the problem for most people. 21.4 implements "portable dumping", which eliminates the problem altogether. We recommend you use the 21.4 binaries, but you can use the 21.1 binaries if you are very paranoid about stability. *Note Q6.0.3::.
