I have recently upgraded from Version 8 to Version 12. I want to uninstall V.8 but Windows Control Panel - Add/Remove posts the following error message when I try:

Error Code: -5004 : 0x80070005
Error Information:
>SetupDLL\SetupDLL.cpp (1924)
pAPP:NetObjects Fusion 8
PVENDOR:Website Pros
PGUID:86EF6C1E-9091-4E08-860B-EF3917A15844
$7.1.100.1248
@Windows XP Service Pack 3 (2600) IE 8.0.6001.18702

Also, which is even more annoying, the disc space occupied by V.8 has gone up from 200MB to 2,668MB!

Anyone know how I can delete V.8.? Preferably without disturbing V.12. as I use this to maintain a charity website.
