Windows 10下如何查找小型启动器.exe下载的完整安装包位置

Great question! I’ve tackled this exact issue with tiny bootstrapper installers like the 2MB Kaspersky setup.exe—these small executables just pull the full installation package from a server, so here’s how you can grab that offline-friendly installer file:

Common Methods to Find the Downloaded Installer Path #

• Check Windows Temporary Folders (Quick & Simple)

  1. Before running the 2MB setup.exe, open your system’s temporary directories using these shortcuts:
     • Press Win + R, type %temp% and hit Enter (user-level temp folder)
     • Or use %localappdata%\Temp for another common temp location
  2. Sort the files/folders by Date Modified so new items pop to the top.
  3. Launch the bootstrapper and watch for new folders/files appearing as the "downloading" progress runs. For Kaspersky, you’ll often see a folder named something like Kaspersky_XXXX (with random alphanumeric suffixes) containing the full installer files.
  4. Critical Note: Copy the full installer immediately once the download finishes (before the "installation in process" step completes)—many bootstrappers auto-delete these temp files after installation wraps up.

• Use Process Monitor for Precise Tracking
  If the temp folder method doesn’t work (some bootstrappers use obscure paths), Process Monitor (ProcMon) is your best bet:

  1. Launch ProcMon and set a filter for the bootstrapper process (the 2MB setup.exe you’re running).
  2. Filter for file operations like CreateFile and WriteFile, then look for files with extensions like .msi, .cab, or a full setup executable. The "Path" column will show you exactly where the installer is being saved.
  3. This method cuts through any hidden temp paths and ensures you don’t miss the file.

Pro Tips #

• If you can, pause the installation right after the download completes—this gives you plenty of time to locate and copy the full installer without worrying about auto-deletion.
• Check the bootstrapper’s properties (right-click > Properties > Digital Signatures/Details tab) for clues about the installer’s naming convention, which can help you spot it faster in temp folders.
