I will try explaining this to the best of my ability.
First some PC info ... HP Compaq 6200 with Win 7 Pro upgraded to Win 10 Pro. Security updates, etc. are up to date. Any other info will be provided on request.
I recently tried updating from 7.58 to 7.83. I could get it to install BUT ... during install the "Destination folder" defaulted to the 7.58 version folder, which I have now been told is correct.
BUT, her comes my problems ... I've previously been told mIRC needs to be installed in the root (C:\) directory so, I named a new folder (Realm2026) and re-directed the install to THAT folder. It installed to that folder and after choosing the network, I was able to connect but, none of my settings were there. so, I proceeded to adding channels (rooms) manually and drudging through other settings to make it look like the old version.
It was at this time I was told by another experienced user on that network that I should have left it install to the recommended directory and that I should do so WITHOUT deleting the previous install and to make a Zipped backup of 7.58 version, which I did. It installed to the desktop.
I then tried to reinstall the7.83 script, which defaulted to C:\Realm2020\Realm2026\mIRC ... Realm2020 being the version7.58 script folder.
Now, defaulting to that destination, all it did was add a folder labeled Realm2026, which had the mIRC folder in it. There are several other folders along with the realm2026 folder that are NOT in the mIRC 7.83 folder.
My question to start with is this ... Is there an easy way to add all the old settings to the new version? What should and shouldn't I delete? If I need to do so, how can I get rid of the Realm2026 folder label? I would like to name the new Script Realm2026 but, don't want to cause issues doing so.
I am open to all suggestions concerning this.

TIA
