So, what happens if Windows cannot open an. Many users have been complaining about this in Windows forums and looking for how to fix an. Windows 7, 8. As with basically every Windows issue, solutions abound. At least one of the solutions given should resolve your situation.

It is associated with the Windows operating system and is expected to just work. So, when an executable file is clicked and nothing happens, it should be surprising. There are several reasons why clicking an. Here is a rundown of the major causes:. The issue is not too difficult to resolve. You can use the best workarounds and hacks given in this guide. This is obviously unacceptable since using programs is the whole point of a computer.

When this happens, you must find a solution immediately. There is a wide variety of malware out there, and some malicious entities can prevent you from opening. If your PC has been invaded by malicious software and you cannot open executable files, this is probably the cause.

Most importantly, full source code for PEDUMP is available for download fropm the link at the top of this article, so you have a working example of the concepts and data structures described here. Microsoft introduced the PE File format, more commonly known as the PE format, as part of the original Win32 specifications. It was natural for these developers to use existing code to quickly bootstrap the new Windows NT platform.

The term "Portable Executable" was chosen because the intent was to have a common file format for all flavors of Windows, on all supported CPUs. To a large extent, this goal has been achieved with the same format used on Windows NT and descendants, Windows 95 and descendants, and Windows CE. You can get an idea of how old the COFF format is by looking at some of its fields, which use octal encoding!

The addition of bit Windows required just a few modifications to the PE format. No new fields were added, and only one field in the PE format was deleted. The remaining changes are simply the widening of certain fields from 32 bits to 64 bits.

In most of these cases, you can write code that simply works with both 32 and bit PE files. They both use the exact same PE format. Even the DLL file extension is artificial.

You can have DLLs with entirely different extensions—for instance. OCX controls and Control Panel applets. A very handy aspect of PE files is that the data structures on disk are the same data structures used in memory. Loading an executable into memory for example, by calling LoadLibrary is primarily a matter of mapping certain ranges of a PE file into the address space.

The key point is that if you know how to find something in a PE file, you can almost certainly find the same information when the file is loaded in memory. It's important to note that PE files are not just mapped into memory as a single memory-mapped file. Instead, the Windows loader looks at the PE file and decides what portions of the file to map in. This mapping is consistent in that higher offsets in the file correspond to higher memory addresses when mapped into memory.

The offset of an item in the disk file may differ from its offset once loaded into memory. However, all the information is present to allow you to make the translation from disk offset to memory offset see Figure 1. Figure 1 Offsets When PE files are loaded into memory via the Windows loader, the in-memory version is known as a module.

This is a point worth remembering: given an HMODULE, you know what data structure to expect at that address, and you can use that knowledge to find all the other data structures in memory. This powerful capability can be exploited for other purposes such as API interception. A module in memory represents all the code, data, and resources from an executable file that is needed by a process.

Other parts of a PE file may be read, but not mapped in for instance, relocations. Some parts may not be mapped in at all, for example, when debug information is placed at the end of the file.

A field in the PE header tells the system how much memory needs to be set aside for mapping the executable into memory. Data that won't be mapped in is placed at the end of the file, past any parts that will be mapped in.

Within this header file, you'll find nearly every structure definition, enumeration, and define needed to work with PE files or the equivalent structures in memory. Sure, there is documentation elsewhere. H is the final word on what PE files look like. There are many tools for examining PE files. I particularly like Depends because it has a very succinct way of examining a file's imports and exports.

Before I start looking at the specifics of PE files, it's worthwhile to first review a few basic concepts that thread their way through the entire subject of PE files.

In the following sections, I will discuss PE file sections, relative virtual addresses RVAs , the data directory, and how functions are imported. A PE file section represents code or data of some sort. While code is just code, there are multiple types of data.

Generally speaking, all the code or data in a section is logically related in some way. At a minimum, there are usually at least two sections in a PE file: one for code, the other for data. Commonly, there's at least one other type of data section in a PE file.

I'll look at the various kinds of sections in Part 2 of this article next month. Each section has a distinct name. This name is intended to convey the purpose of the section. For example, a section called.

Section names are used solely for the benefit of humans, and are insignificant to the operating system. Microsoft typically prefixes their section names with a period, but it's not a requirement. While compilers have a standard set of sections that they generate, there's nothing magical about them. You can create and name your own sections, and the linker happily includes them in the executable.

For instance, the statement. Most programs are fine using the default sections emitted by the compiler, but occasionally you may have funky requirements which necessitate putting code or data into a separate section. Sections don't spring fully formed from the linker; rather, they start out in OBJ files, usually placed there by the compiler. The linker's job is to combine all the required sections from OBJ files and libraries into the appropriate final section in the PE file.

For example, each OBJ file in your project probably has at least a. The linker takes all the sections named. Likewise, all the sections named.

Code and data from. LIB files are also typically included in an executable, but that subject is outside the scope of this article. There is a rather complete set of rules that linkers follow to decide which sections to combine and how. A section in an OBJ file may be intended for the linker's use, and not make it into the final executable.

A section like this would be intended for the compiler to pass information to the linker. Sections have two alignment values, one within the disk file and the other in memory. The PE file header specifies both of these values, which can differ. Each section starts at an offset that's some multiple of the alignment value. For instance, in the PE file, a typical alignment would be 0x Thus, every section begins at a file offset that's a multiple of 0x Once mapped into memory, sections always start on at least a page boundary.

That is, when a PE section is mapped into memory, the first byte of each section corresponds to a memory page. Likewise, the.
