Hi, It appears that this IE8 addon does not install correctly once integrated into a WinXP source. It seems to have slipstreamed ok using RVM's integrator but after you install windows with this addon integrated you get the following message, Ordinal Not Found The ordinal 410 could not be located in the dynamic link library urlmon.dll. I had the same in the previous release but thought it might have been fixed in the release. Please can you check this out as soon as you have time.
