Windows app virtualization
ExeWrap virtualizes a Windows application — its DLLs and data files — into a single self-contained executable that runs entirely from memory. Nothing is ever unpacked to disk. Win32 & Win64, any native compiler.

In-memory virtualization
ExeWrap maps your app and its dependencies straight into memory and serves its data from a virtual file system. No installer, no scattered files, no temp extraction.
Your app, every DLL it imports and its data files are packed into a single output executable. ExeWrap auto-detects the co-located dependency closure — no manifest to maintain.
A reflective PE loader maps every bundled module straight into memory — relocations, imports, TLS, x64 SEH unwind and all. The payload never touches disk, not even %TEMP%.
Bundled config, assets and databases are served from a virtual file system: open, read, enumerate, memory-map — even copy-on-write writes, kept in RAM or persisted to an encrypted cache. Registry keys can be bundled the same way — enough for an in-process COM server to activate on a machine where nothing was installed.
Every box is AES-256 encrypted out of the box — the payload and the file directory, so names, sizes and contents are all hidden, never a plain zip. Password-protect it (PBKDF2, key never stored) when it should run only for someone with the secret.
Ship a small signed .xupd patch beside the box to override bundled files without rebuilding. RSA signatures keep forged or tampered patches out.
ExeWrap is a PE loader, not a language runtime. C, C++, Rust, Go, Delphi — any native Windows executable boxes the same way, in-process COM servers included. (.NET / CLR and out-of-process COM are out of scope.)
How it works
Drop your compiled Windows app onto ExeWrap or pass it on the command line. The import closure beside it is detected automatically.
Add data files or folders. Encryption is on by default — opt out for a plain build, or password-protect it — and embed a public key if you plan to ship signed patches.
Out comes a single executable that runs your app from memory on a clean machine — no install, no scattered DLLs, no extraction.
