Use the binary files I uploaded! I've sorted them and patched them so they can run under XP! (For use the 32bit wem-(un)packer releases.)
List: WemTool_XP_compat_files.7z (Although this pack was uploaded directly for Masquerade.) You can download the XP compatible "xdelta.exe" from the original
site (marked "i686"). Or you can use the files below. (After running, copy them from the TEMP directory.) The my uploaded "mp.exe" XP-compatible.
wempack_x86_hdiff.7z
wempack_x86_xdelta.7z
If all *.exe files, fixed for XP, run without errors, then the batch script should run without errors when compressing and decompressing *.wem files. (I haven't even experimented with this yet.)
