RTE 602 again

[hobferret]

Hi, me again, a couple of years back I asked if there was any reason why when unpk execryptor I should get a runtime error. Every one I do has the same result
Well, now I tried something different. Installed an old copy of XP with no service packs and guess what NO RUNTIME ERROR
However, when I then try and run it with a later XP the God darn runtime error is back
Any one have any ideas please??

.rdata section flags value has to be 0x40000040 and any section with executable flag cannot have writable flag in PE header.

@hobferet I remember that problem happening on SP2. Yes it was caused by an incorrect PE flag. I used to play around with self-modifying code in Delphi.
