if for some reason, your registry file (nsreg.dat) is corrupted, and you install a patch to patch files, your files will all be deleted. To reproduce (must have a corrupted registry): 1. trigger http://warp/u/cathleen/test/xpinstall/patch/install.jar to install a file in c:\patch\f1.txt 2. trigger http://warp/u/cathleen/test/xpinstall/patch/patch.jar to patch f1.txt 3. noticed that nothing is left in c:\patch We don't need to track the return value for VR_Install in nsInstallPatch::Complete() because it will cause abort,and in turn the file gets deleted. Patching is not a reversible process, if the registry update fails, we leave the patched/updated file.

I believe Dan has a simple fix for this on his machine.

Dan, you got the fixes on your machine. Can you check them in?
