Hi, yesterday I installed the program for the first time. The presentation gave me problems and crashed after half an hour of operation (I have sent log to hotline). After which I uninstalled pvsol, downloaded it again, and installed it again several times (no less than 10). My computer has not antivirus or firewall, only windows security. Since I reinstalled it, if I click on the icon, it does nothing, it fires for 10 seconds and nothing.
