#131 Not a valid Win32 application

[Paul]

Version: Dev-Cpp 5.7.1 MinGW 4.8.1 (Portable) and Dev-Cpp 5.7.1 TDM-GCC x64 4.8.1 (Portable)

OS version: Windows XP 32 bits

Error reported: When I try to execute a .exe file I allways get the same error message: "Not a valid Win32 application", devcpp.exe, devcppPortable.exe, even the .exe files inside the compiler forlder, it seems all files are not valid Win32 applications.

Steps needed to reproduce the problem: Execute any .exe file.

Could it be that you unpacked the portable .7z archive using old version of 7-Zip (e.g. 7-Zip version 4.xx) or using a different unpacker (not 7-Zip)?
The portable version needs 7-Zip version 9.20 or higher to be unpacked properly. It's because a newer (and better) compression algorithm is used by it (LZMA2 instead of LZMA, to be specific).

( I know this because I already investigated it here: https://sourceforge.net/p/orwelldevcpp/forums/general/thread/c22b0eb7/ :) )

Yes, that fixed the problem. You should add a note indicating 7z latest version is required in order to be able to unzip the files, or just zip the files with a standard algorithm supported by any .zip application.

7z should fail or show an error message instead of unzipping files pretending everything worked fine. No error messages in a situation such like this is really a bad, bad thing.

Thanks, I love Dev-C++ Portable :)
