This program remaps its image to prevent the page protection of pages contained in the image from being modified via NtProtectVirtualMemory.

i tested it working well in x64 mode but i need x86, it always crash here:
status = fpRemapRoutine(pRemapRegion);
Is this code compatible with VMProtect / Themida?
Step 4 of the implementation says "The remap routine maps a view of the entire section and copies the contents of the image to the view. This view is then unmapped.".
Why is this necessary? I took out this logic in the code and the program crashed with a memory access violation.
Could you explain what this step accomplishes? I'm a beginner at this. Thank you very much.
I've just compiled the sample under VS 2017 x64 and I get the following error:
=================================================================
Section Base Address Size Rva
-----------------------------------------------------------------
.text 7FF75AA91000 DA91 1000
.rdata 7FF75AA9F000 FD40 F000
.data 7FF75AAAF000 6D8 1F000
=================================================================
Error: .rdata or .data are not aligned to system allocation granularity.
What would I need to change to make it work under VS 2017 Compiler?
As the title is, do you consider that:
#define SCNVIEW_MASK_READ 0x1
#define SCNVIEW_MASK_WRITE 0x2
#define SCNVIEW_MASK_EXECUTE 0x4
if (pSectionHeader->Characteristics & IMAGE_SCN_MEM_READ) mask |= SCNVIEW_MASK_READ;
if (pSectionHeader->Characteristics & IMAGE_SCN_MEM_WRITE) mask |= SCNVIEW_MASK_WRITE;
if (pSectionHeader->Characteristics & IMAGE_SCN_MEM_EXECUTE) mask |= SCNVIEW_MASK_EXECUTE;
// then map `mask` to `PAGE_*`
