I don’t think there’s a way for you to do as you propose. The upgrade pricing only applies to PL5 for you, so going from PL5 to PL6 on the grounds that you bought PL5 within a few weeks of the release of PL6 very likely isn’t going to be a free transition. You’d have to plead your case with DxO support (support.dxo.com).
I expect it’s decided case-by-case, per the refund policy DxO has published. You bought PL2 at full price, and then PL3 was released a short time later, so getting a free upgrade to PL3 is fair. If you were to pay full price for PL5, and then a very short time later PL6 was released, I suppose you’d be offered that for free or you’d be able to ask for a free upgrade. But upgrade pricing is based on what you’re upgrading from. In the scenario you’re considering, you’re upgrading from PL3. You can get PL5 at the upgrade discount. You probably won’t get PL6 for the same price - you’d have to pay more so that you end up paying full price for PL6 and not paying for PL5. Just my guess.
Consider this, too: if PhotoLab goes on sale for 30% off and you buy it, then a 50% off sale is offered a week later, will DxO increase your discount to 50%? Discussions on the forums here indicate no, unless you haven’t activated the license yet. Then maybe.
You only get a free upgrade if you own the previous version for less than a month. That was also the case when you upgraded from PL2 to PL 3. There is a 30 day free trial for PhotoLab. It is not a refund since you don’t have to purchase it for the free trial. PL6 six will be released in five weeks. If you wait until the annual Black Friday sale you will be able to get PhotoLab 6 at the lowest price of the year.
I have never tried that specific scenario. I am also not certain whether its a 30 day upgrade window or less then 30 days. But that sounds correct. However, If you wait for Black Friday I believe the purchase price for PhotoLab 6 Elite will be even less. I assume you are referring to the the Elite version. If you are not, you should be.
Second, what operating system are you using? On a PC, PhotoLab 5 or 6 requires Windows 10 or later. If you are on a Mac which version of MacOS do you have installed. DxO only supports 2 previous versions of MacOS. I believe Catalina is still supported for PL 5 but will not be supported for PL 6.
Definitely buy ONLY on black Friday sale in November. This is the only time where you get 50% off and don’t consider the 30% discount when the new version 6 comes out in October, you won’t get a refund. I have been bitten by this stupid policy to buy in August then the upgrade in October at 30% to then see 50% in November. I wasn’t aware and DxO was extremely inflexible to be polite… It’s a good product but customer is not King here.
PL/SQL enables users to send a block of statements to the database, which significantly reduces traffic between the app and the database. It is also possible to run PL/SQL on any operating system (OS) or platform where Oracle Database runs .
As @KeithRJ pointed out, you’re posting on an incorrect forum. The PL often referred to on this forum stands for PhotoLab, an image processing program owned and developed by DxO which has nothing to do with PL/SQL.
