I, too, am having this problem. I'm using: 1. nLite v1.0 beta 5 2. Windows XP Pro (VLK) with SP2 integrated o.k., i replaced makecab into nlite\data like suggested. Still having the same problem with makecab.exe crashing during Finalizing... just making iso = no problems. remove components + make iso = makecab crash integrating drivers + remove components + make iso = makecab crash integrate drivers + remove components + UA Setup + make iso = makecab crash in short, anything addition to make bootable iso = makecab crash Question: What is the makecab.exe for? Question: If I cannot Remove Components, then what is the point of nLite? -- sorry if question #2 seems rude, i'm exasparated at trying this. So many others seem to be able to use this w/o error; and, I would like to as well. ==Edit again== After Checking Event Viewer, I find this Faulting application makecab.exe, version 5.1.2600.2180,faulting module makecab.exe,version 5.1.2600.2180, fault address 0x00013d45. Also these fault addresses: => 0x00013bbb => 0x00013ad3 ==Edit...yes, again == OK, dug out my clean/gold xp (ie. no SP) .. same problems as above with makecab.exe from the original xp disc, not SP2's version.
