Put together, “vsprecleanvsexe exclusive” suggests that during the pre-clean phase, Visual Studio or MSBuild cannot delete or overwrite a file because another VS-related process has it open with exclusive read/write permissions.
VSPreclean is a utility often used by developers to clean up Visual Studio solution and project files. Its primary purpose is to remove "exclusive" or locked build configurations that can cause errors when upgrading projects or moving them between different environments.
Visual Studio 2012 introduced parallel project builds by default (/m switch in MSBuild). Parallel builds sometimes cause race conditions where one build process tries to clean a file while another is still writing it. Later versions of VS (2015+) improved file lock handling and retry logic.
Purpose: Its primary function is to "pre-clean" the environment by detecting and deleting pre-release components, SDKs, and residual data like temporary files or caches from prior installations.
Usage: This utility is typically executed automatically by the main installer bootstrapper (such as vs_ultimate.exe or vs_professional.exe). It is not generally intended for manual user execution unless troubleshooting a specific setup corruption. vsprecleanvsexe visual studio 2012 exclusive
Distribution: It was notably included in "MSDN Disc 5095" and various Developer Preview releases for Visual Studio 2012. Common Issues and Solutions
Users frequently encounter this file when the Visual Studio 2012 installation hangs or fails.
Corrupt Installer Media: Errors like "vs_preclean_vs.exe is missing" or "not valid" often stem from a corrupt ISO or installation package.
Fix: Download a fresh copy of the Visual Studio 2012 Update 4 ISO from official Microsoft sources. In exclusive mode, even leftover environment variables from
Compatibility Mode Conflicts: If the installer fails immediately after the pre-clean step, it may be due to "Program Compatibility Mode" being active on the installer file.
Fix: Ensure compatibility mode is disabled for the setup executable and consider stopping the "Program Compatibility Assistant Service" in services.msc.
Forced Uninstallation: If standard uninstallation through the Control Panel fails, you can use the main setup executable with specific flags to perform a "clean" removal: Command: vs_ultimate.exe /uninstall /force. Support Status
Official support for the Visual Studio 2012 IDE and its associated components ended on January 10, 2023. Microsoft recommends upgrading to a newer version, such as Visual Studio 2022, for continued security updates and better stability. But no other process exists—only leftover variables

Based on common naming conventions and Visual Studio 2012’s Performance Profiling Tools (part of the Diagnostics Tools under Visual Studio Premium/Ultimate), here’s a clarification and a helpful report on the actual tools you probably meant:
In exclusive mode, even leftover environment variables from a previously crashed or improperly closed profiling session will block new profiling attempts. This is where vsprefixcleanup.exe becomes indispensable.
Without cleanup, you might see:
Failed to enable profiler. Exclusive mode already active by another process.
But no other process exists—only leftover variables.
