I've been running cf8 on a windows webserver 2008 with IIS7.5 and have just installed cf11. The install completed successfully to the point of opening cfadmin and then failed. On looking in the web root directory as set in IIS, the old CFIDE folder had not been updated, so cf11 was attempting to use the cf8 version.
I renamed the old cfide folder to cfide08, uninstalled cf11 and tried reinstalling it again - but still no cfide folder was created for cf11, and I couldn't open cfadmin. The cfide folder does get created in c:\ColdFusion11\cfusion\wwwroot\cfide
Has anyone else experienced this, or know how to fix it?
