Windows 64bit v21.1.53 msi scans OK with EST v14.0.22.0 and virus total VirusTotal
Will check running the file to install Manager.
Edit
For me Manager x64 v21.1.53 installed without error while running ESET. On this machine I’m running Windows 7 professional and install Manager in “C:\Program Files (x86)\Manager” (via Windows Installation (not portable) - #6 by Patch ) but I’m not sure how that would effect an ESET virus detection.
@Abeiku In your Eset error message a “file” link reference is shown. Have you clicked on that link to find out which file is tripping the virus detection?
