Bob, I have got a response from MSI newsgroup. It looks like that problem is caused by file sequence numbers.
In my base and upgrade images, different files shares the same sequence numbers. The "error reading file" is a new file, but has the same sequence number as an old file in the base image. I use PatchWizard as it is easy to create wxs file, diff is much better now due to unique file ids in WiX 3.0, but it looks like sequence is still a problem. I have tried to use WiX only patching, but this does not support deleting files. I reckon that I have to work out deleted files and list them in the patch wxs file. Maybe this is the only option that works?
