I initially installed Music Maker Plus with no difficulty. I upgraded to Music Maker Premium and tried to install it over the original. For some reason it said that the versions were the same, they are not. The file sizes are different. I uninstalled the Plus version and when I try to install the Premium Version I get the Installation Error Code 1638 Another version of this product already exists. To configure or remove the existing version of this product use Add/Remove Programs. However Music Maker Plus is no longer listed under Add/Remove Programs. I have tried to manually delete the files and remove the Registry References with no success.
I have also tried to reinstall the Plus version, but now cannot and get the same error.
Any thoughts about how to get around this vexing issue and get the Premium version installed?
Thanks
