Plugins in 32-bit vs 64-Bit Paintshop Pro

Plugins in 32-bit vs 64-Bit Paintshop Pro

32-bit vs 64-bit | Converting Information

In order to know which programs to run in 32-bit, your OS has to open each program into a “Process”. This process can be either 32-bit or 64-bit, but not both. So, once again, we see strict separation between the two.

What’s more, plugins are not standalone programs… they “plug in” to a program, and that program is then responsible for that particular plugin. This means the plugin is opened in the exact same process as the program that called it—so, a 32-bit process can only open a 32-bit plugin because it cannot run 64-bit code, and vice-versa.

I sense another question coming here, something like, “If my 32-bit plugins won’t ever be converted to 64-bit, what’s the point of moving to 64-bit at all?”

We already know 64-bit allows larger memory addresses, which means more access to RAM. For photographers, this means you can hold larger images or files with lots of layers without forcing the program to come to a grinding halt. I won’t promise it’ll be super-fast, but it won’t randomly stop responding. Anyone who has ever tried working on huge images in 32-bit PaintShop Pro will know exactly what I’m talking about.

And in some very few and rare cases, because the processor can hold more information, it can perform some calculations faster and with fewer cycles than 32-bit can.  Though, often, you probably won’t notice it.

So, combining the two, 64-bit makes it possible to work effectively on larger images without the program stalling out and you might see one or two optimized filters finish faster.

“Well that hardly seems worth it!” I hear you cry.  Sadly, photo-editing and is just one type of program that benefits from a move to 64-bit systems. Not to mention they’re quickly becoming the only systems sold, with 32-bit going the way of the dodo… like the old 16-bit systems before them.

Eventually 64-bit is all there will be… until, of course, the industry makes the jump to 128-bit. So it’s an unfortunate reality that, at some point, our favorite 32-bit plugins won’t work at all — if you’re the type to keep up with the latest advances in technology. Corel provides both 32-bit and 64-bit versions of PaintShop Pro, to help accommodate for those plugins that have not yet been recompiled or rebuilt by their creators or no longer receiving support.

If you’ve made it to the end of this longer technical answer, I commend you and hope I’ve helped to shed some light on the differences between 32- and 64-bit and why we can’t just run our old 32-bit plugins in 64-bit PaintShop Pro.

Thanks again for reading and stay tuned for my next post here on Points of View!

    I have found that you cannot install the 32 and 64 bit version. If you have 64 bit installed and try and install the 32 bit – it automatically proceeds to uninstall the 64 bit. What the 64 bit installation does do is copy the installation files to the Program files x86 folder but it’s not installed.

    So far i am very impressed with the new layout and attempt to really jack up the software, unfortunately without being able to use the my old plugins – I’m not really interested in upgrading. If I can find a way to get my plethora of plugins to work perhaps on the 32 bit – but uninstalling and trying to install the 32bit version is proving to be a time consuming nightmare.

    I have a 64-bit system and installed PSP2019. The scanner won’t work. I was told to install the 32-bit version. But how do you do that? I see no option for that.

      Hello Maurice,

      The 32-bit installer is a separate file from the 64 bit version, and would be a separate download link included with your purchase. Just check the email containing your order details, and you can download and install the 32-bit version as well as the 64-bit version!

    When you mention that the developers of the 32 bit apps may have vanished does that make the aps unstable if they are not receiving updates?

    Had a problem with reinstalling my PaintPro x9 software today – could not download new copy.
    “Your system has not been modified” apparently a very common issue – but solutions not readily available in your support forum.
    Left a message with support 12 hours ago , never heard a word. Searched a long time for an answer. Your forums gave me little answers, except to discover issue was common.
    Finally thought I would search for a removal tool which I had read about. – it worked great.
    Except that the tool initially told me there was no Pantpro x9 software – I clicked on clean anyhow and it wiped out about 7 files. Their removal seemed to make it able to install a new copy.
    The “Your system has not been modified” wa gone.!

    My comment, if you have no support on Saturdays could you not get the forum full of answers to very common issues, so that we can fix things ourselves easily without spending hours.

    There may be 10 or 15 common problems, you could write out solutions to them.
    The FAQ’s do not deal with any support issues to speak of.

    If you could pass this along, I will feel I have not wasted my time writing this whole thing out.

      Hi Brian, apologies for the delay here. In terms of maintaining compatibility with those 32-bit plugins, that will be up to the individual 3rd party developers. Sorry to hear you had some troubles getting PaintShop Pro installed. There may have been some leftover files from a previous install that jammed things up, but that cleanup tool works wonders. Our Knowledgebase ( does answer common technical FAQs, so I’ll definitely talk to our support team about adding answers to those questions to the Knowledgebase. Thanks for the suggestion, Brian!

    A shame, because the missing Gradfilter plugin is a upgrade-dealbreaker for me.
    I just have to stick with v2.1.2,10 – 32bit on my 64bit machine.
