Probabyl tax from installing application from some not serious web.

Anyway thank you for your time and help.

Best regards.

Hi freename, that's probably your anti-virus interfering with the installation. Are you possibly running ESET? That particular anti-virus checker mistakenly identifies moi_lib.dll as containing a virus because it categorizes anything wrapped with the WinLicense anti-hacking mechanism as a virus. There should be some way you can turn it off temporarily or tell it to make an exception for the MoI trial.

Also the alternate "no save" trial version is not wrapped with WinLicense and so probably won't have the same installation problem.
