Applications crash on ARM64-based Windows devices

What the tool does

• Verifies that the system is running Windows on an ARM64 architecture.
• Scans the Windows System32 directory for AMD64 versions of Microsoft Visual C++ runtime libraries (version 14.44.35211.x).
• If the tool finds incorrect files, it:​
  • Creates a local backup of the affected DLLs before making any changes​
  • Removes the incorrect AMD64 files from the system directory​
  • Installs the correct ARM64 Visual C++ runtime package using Microsoft's official redistributable
• Verifies cleanup and automatically deletes temporary files used during the repair process.
• Logs all operations to a file placed next to the executable (FixVCRuntime.log).

When to use this tool

Run this tool only if:

• You are using an ARM64-based Windows device, such as the Surface Pro X or Lenovo ThinkPad X13s.
• Acrobat or other applications report missing or invalid Visual C++ runtime errors after installation or update.
• Adobe Support or IT administrators have directed you to repair Visual C++ runtimes.

Safety and validation 

• The tool only modifies Microsoft Visual C++ runtime files that are verified to be incorrect for the AMD64 architecture on ARM64 systems.
• The tool backs up all the affected files before removal. 
• The installer included is the unmodified, digitally signed Microsoft Visual C++ Redistributable package.
• No other system or application files are changed.

Log file

A log file is created in the same directory as the executable (for example,
C:\Users\<User>\Downloads\FixVCRuntime.log).
It includes detailed timestamps of detected files, backup operations, and installer results.
If requested by support, you can share this log to confirm successful repair.

Version information

Note: Running this utility on non-ARM64 or unsupported systems will have no effect. Use only as directed by Adobe Support or IT administrators.
