This error typically occurs when trying to install drivers for CH340/CH341 USB-to-Serial adapters, commonly used with Arduino, laser engravers, and 3D printers. It indicates the installer cannot extract or write the necessary 64-bit setup files to a temporary directory. Quick Fixes
Run as Administrator: Right-click the installation executable (e.g., CH341SER.EXE) and select Run as administrator.
Manual Extraction: Instead of clicking "Install" on the first prompt, find the extracted folder (often C:\WCH.CN\CH341SER\) and manually run DRVSETUP64.exe with admin privileges.
Disable Antivirus: Your security software may be blocking the creation of .exe files in temporary folders. Temporarily disable it and try the install again. In-Depth Solutions If the quick fixes don't work, try these technical steps: Driver Clean-Up: Open Device Manager.
