hi @fanin61074 ,


The error "icwrapper.dll failed to register" in Quick-Books typically occurs during installation or updates and is related to a Dynamic Link Library (DLL) file not being properly registered. This issue can stem from administrative permission problems, corrupted installation files, or conflicts with other software.


  1. Run as Administrator: Right-click the Quick-Books installation file and select "Run as Administrator."
  2. Reinstall Microsoft .NET Framework: Download and reinstall the latest version of .NET Framework from the official Microsoft website.
  3. Use Quick-Books Install Diagnostic Tool: Download and run this tool from the Intuit website to automatically fix common installation errors.
  4. Manual DLL Registration: Open Command Prompt as an administrator and enter regsvr32 icwrapper.dll to manually register the DLL file.

These steps should resolve the error and allow Quick-Books to install or update correctly.
