Dear All, After thorough testing, I've confirmed that there is an error in cablib.dll or its implementation in nLite. I've tested it in nLite Versions 1.4.8, 1.4.9 and 1.4.9.1 Whenever I go to the point where the driver.cab extraction begins, the error pops up: I also tried to substitute the cablib.dll with the latest version (9.9.0.0), but when it is replaced, nLite application completely fails. " X:\xxx\i386\driver.cab is damaged. This is a very serious error ... " Otherwise, I think that nLite is a great software. My environment is: Windows XP SP3 32-bit freshly installed on VMWare with 512 Mb RAM. Trying to add up more items (addons) to Windows XP SP3 32-bit version, plus some parameter tweaking. Hope that this information helps.
