Still having problem while trying to install the new Demo...

I posted in the original thread yesterday about when I try to install the new demo that it tells me to uninstall the "pre-release version" first and won't let me install. Well...I took suggestions of deleting all my temp files and then looking in the registry for FSX related stuff. Well, I did both and even downloaded Registry Mechanic which found a TON of FSX remnants left. I have gotten rid of everything in the registry that the program can find. I still CANNOT install the new demo. I have deleted it. I would download again if I can get this straightened out. I want to see if its improved on MY system. Anyway, my topic got buried in that original thread so I thought I would make a new one.[/a][a href=http://library.avsim.net/search.php?CatID=root&SearchTerm=fritsche&Sort=Added&ScanMode=0&Go=Change+View]My paints...[/a][a href=http://www.airliners.net/search/photo.search?photographersearch=Danny%20Fritsche%20-%20Airplanespotters&distinct_entry=true]See me at Airliners.net...[/a][a href=http://www.airplanespotters.com]Also at airplanespotters.com...[/a]
