LTspice installation failing on Windows 11 with Error 1723 - IsWine.dll

Category: Software

tried installing the latest LTspice (version 26.0.2.1) on my Windows 11 laptop, but the installation keeps failing with Error 1723 "There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run".

generated a verbose MSI installation log and got this:

Action: IsWine.dll
Entry: IsWineDetected
Error code: 1157

CustomAction IsWine.dll returned actual error code 1157

I am using Windows 11 Home Single Language, Version 25H2, OS Build 26200.8875.

Could you please let me know how I can resolve this issue or if there is an updated installer available that fixes the IsWine.dll problem?
