Hi,I had to reinstall FS9 but I have troubles:I removed FS9 via the setup procedure on the CD's and reinstalled it, but now the FS9.1 update refuses to install because "it is already installed". How can I solve this ?Thanks in advance,Hugo

When you uninstall FS9, at a minimum you need to remove all the fs9 dll's from the modules folder and all the fs9 dll's and exe's from the main FS9 folder. In addition, FS9 may leave it's reg entries behind in HKLM/Software and HKCU/Software. If you're trying to retain add-ons you've installed, look at the dates of the dll's in the modules folder--the 9.1 dll's all have a date of '05 in common--I believe August or September. Just about anything else is likely there due to an add-on.The Uninstall process used by most uninstallers usually won't touch dll's that are different from those originally installed by the installer, kind of like the way our bodies kick out foreign bacteria--the uninstaller doesn't recognize the dll's as it's own. And quite often uninstallers leave the reg entries behind. Hope this helps a little.-John

The 9.1 patch creates a folder called "Backup" in the main FS9 folder. That has to be manually deleted also before reinstalling the patch (or else it thinks it's already installed).Doug Edited because I can't spel

Hi John and Doug,Deleting the backup map solved the issue!Thanks,Hugo
