\n
- Deleting the
%LOCALAPPDATA%\\\\Lumerical<\/code> folder and the contents of the%TEMP%<\/code> folder.<\/li>\n- Dropping to 1 process and 1 thread in the Resources tab.<\/li>\n
- Switching to local computer in Resources → Edit.<\/li>\n
- Making a new
.lms<\/code> file with the same structures.<\/li>\n- Running another trivial example.<\/li>\n
- Reinstalling the 2015-2022 C++ distributable: https:\/\/learn.microsoft.com\/en-us\/cpp\/windows\/latest-supported-vc-redist?view=msvc-170<\/a><\/li>\n
- Disabling Microsoft Defender Antivirus<\/li>\n
- Checking p0 log file in the sweep folder created by Lumerical: it says simulation successfully completed, but the job detail is as above.<\/li>\n
sfc \/scannow<\/code> with administrator CMD didn’t return any errors.<\/li>\n<\/ol>\n<p><p>I see the same message on a different computer. Here’s an example:<\/p><\/p><\/p>\n
