Rebuild PE headers
If you have an executable which PE header is corrupted (e.g. unpacked exe with OllyDump), LordPE can repair it.
Click on "Rebuild PE", choose the file to repair and click OK.
Compare PE files
It can be interesting to check the modifications applied by LordPE after a repair operation, or just to compare 2 PE files.
To do so, click on "PE Editor", then on "Compare"
