Quote: I usually don't buy upgrade versions because they require previous version to be installed. is this the case with Cyberlink software? If i had to reinstall PD12 upgrade, would I have to reinstall PD11 and then PD12?

Gary, I have seen it both ways. I know that sometimes (and I can't tell when) it only asks for the previous version key; in other cases I have had to re-install the previous version(s). It is a pain if you have to do an upgrade from an old version. Each one requires the "next" one to be installed. .

Anything I post unless stated with a reference is my personal opinion.

Especially when you have 20 or 30 apps to install plus 'updates' to all those apps too. LOL PD11 was my first Cyberlink app and wondering if i should buy the upgrade or full version of PD12. Upgrade is a good price right now. Intel i7 4770k, 16GB, GTX1060 3GB, Two 240GB SSD, 4TB HD, Sony HDR-TD20V 3D camcorder, Sony SLT-A65VK for still images, Windows 10 Pro, 64bit

I'm no expert here but it seems to me that the upgrade is the same as the "full" version based on the file sizes of the upgrade.

It can be a pain, but you save a lot of money by upgrading, especially now with a big discount. Upgrade versions are the same as the full versions except upgrades require you to own a previous version of the software. Sometimes it has to be installed on your machine, sometimes, as noted previously, you need only provide the previous version key. I wasn't planning to upgrade just yet, but the deal on v12, plus I thought I might like to try Color Director, prompted me to upgrade. I'm glad I did, since Color Director seems to work very well.

So which is it with Cyberlink? or does Cyberlink use both methods? Providing the previous install key isn't a big deal, but having to reinstall an old version can be. Buying the full boxed version would be worth the few extra dollars to me in this case.

I'm fairly new to Cyberlink, having started with Version 10 which I used very little of before going back to my previous program, staying there for a year or so and then coming back to PD. As I recall, the previous version has to be installed on your machine to upgrade. It's a pain, but you pays yer money and you takes yer choice. Dell Precision 7510 Laptop

Thanks... I'll just pay the extra $20US or so for the full boxed version. Intel i7 4770k, 16GB, GTX1060 3GB, Two 240GB SSD, 4TB HD, Sony HDR-TD20V 3D camcorder, Sony SLT-A65VK for still images, Windows 10 Pro, 64bit
