Installer takes a long time to load

Maybe this is an Antivirus software issue?

AV software checks every process at start so this delay can be caused by AV check.

Even worse: The A/V software probably recognizes the NSIS installer and unpacks + scans all the files in that installer - just like it does with other types of "archive" files - before it even allows the installer to run. This can take quite a while! And, while the A/V software is blocking things, NSIS has no chance to display any dialog, because the installer process is not even running yet.

You can check this very easily: Just disable the "real-time protection" or "guard" feature of your A/V software and then try again!
