Opto 22 does not currently support PAC Project for Vista. However, I would be interested in seeing if anybody has their system successfully running with Vista.
Perhaps the question should be "Does Microsoft have any plans for supporting Vista?”. PACProject is pretty stable on the Win2000/XP Professional platform, but we have seen various problems with Vista. More than an “Opto problem” it’s a “Microsoft problem”, as Vista appears to be incompatible even with its own bug fixes. The Microsoft equivalent of Hara-kiri is to allow Vista to automatically install its own priority updates.
Although its now pretty difficult to buy a computer with XP Professional, even Bill Gates now accepts the fact that Vista is unsuitable for many applications and its better to reinstall XP as your OEM system. Its legal to do so, fully supported by Microsoft and there is even a new logo for the whole downgrade program. Check out the details from the Microsoft website. Looks like a whole new marketing tool, “Downgradable Software”!
