Installer launches 2 windows after "Previous versions of KVlrc must be uninstalled.": `KVIrc Uninstall` + `KVIrc Setup`

I've noticed that the KVIrc Installer (x64 on win11) launches 2 windows after "Previous versions of KVlrc must be uninstalled.": KVIrc Uninstall + KVIrc Setup.

The former window's process is C:\Users\User\AppData\Local\Temp\~nsuA.tmp\Un_A.exe and the latter is the running installer.

I believe it would be better, if possible, if there was only a single window at a time, first KVIrc Uninstall and then KVIrc Setup, to avoid confusion (because currently the 'Uninstall' window might miss your attention).

I've had this happen to me before as well. However, for me it was not consistent behavior (sometimes on some upgrades it happened, other times it didn't), and I don't know why.
