I have recently purchased the iclone 4.3 upgrade for existing iclone 3 users.

I have endlessly tried to run the download and it gives me this message,

Setup has found a previous installation of iclone 4 in your system.
please uninstall the previous version befire running setup again.

setup program will now terminate.

I have removed all reallusion software etc I did have iclone 4 EX installed ran regedit all folders have been removed, customer services sent me regclean tool that doesnt work that says however no luck tried the cleanreg and it gives me this message "The System cannot find the file specified"

has anybody else had this type of problem?
