No it will not work. That is not the only folder that gets files for a install. There is the C:\Documents & Settings\<User name>\App Data folder which is a
hidden folder that also gets some of the info. Some apps also go further and put info into the Windows folder and the System32 folder.
I have stated it already twice now. There is no way you can just take your current stuff and transfer it. You
MUST get the installers and reinstall the apps.
No other ways to do it. Not even if you copied over the stuff from the App Data folder along with the Program Folder and the registry. You will still be missing stuff that is necessary for operation. Plain and simple. Sorry it is not the answer you want but that is the only answer that there is.
