The standard load address for 64-bit PE executables is the same as for 32-bit, 0x400000. This is also the standard load address for 64-bit ELF executables. If the Wine loader is not relocated, it won't be able to load the majority of PE executables. Ofcourse, there's no problem with 64-bit Winelib executables. As to the more appropriate address, I'm not sure. I just wanted to get it out of the way. I suppose it could be moved to somewhere around or above 0x7bf0000000000000.

The appropriate address needs to be determined from the standard Win64 address space layout. I don't have a Win64 box to check what this looks like though.

Ok, I need some guidance on this. This is the usermode address space layout when running a simple Win64 app:

Some of the commit/mapped areas contain NLS files. As far as I can tell, the TEB and PEB were moved from just-below-2GB to just-below-7TB, while the shared user page and system DLLs like kernel32 and ntdll were kept at just-below-2GB. I think 0x7bf00400 as relocation address for the Wine loader would work fine. If you'd rather see a different load address or want me to investigate something else please let me know.

Yes, it looks like the existing address would work fine. Thanks for checking this.
