Adobe didn't just end support of Flash on Dec. 31, 2020, it killed it.
The company suggested uninstalling the program after Dec. 31, 2020, because Adobe will not issue Flash Player updates or security patches. And then on Jan 12, 2021 Adobe blocked Flash content from running "to help secure your system." Not only did this impact major web browsers by disabling Flash Player content, but it also blocked the libraries from loading in Poser 10 and earlier versions and stopped Reality in Poser from working.
This is because Poser 10 used AIR, a form of Adobe Flash, to manage your runtime.
We have found a few ways around the death of Flash that will repopulate your runtimes, so you can keep creating.
Fixing Adobe Flash in Poser 10
This is the option Poser Support recommends.
First, open Poser.
Then, go to edit > edit > general preferences > library and change library to external.
Renderosity community member bagginsbill found this fix way back in 2014.
First, close Poser.
Next, find your poser.ini file, which is likely in this location: C:/Users/YOURUSERNAME/AppData/Roaming/Poser/10. It could be in AppData/Roaming/Poser Pro/VERSIONNUMBER.
(If you are fearful of editing the file, simply right-click the Poser.ini file, choose Copy then right click again and choose Paste. This will make a backup of your Poser.ini file. Then, you can then edit the original Poser.ini file itself. If anything goes wrong you can delete the edited Poser.ini file and rename the copy back to the original name.)
Then, in poser.ini look for LIBRARY_EMBEDDED_TYPE 0. (Open the Poser 10 file folder, click on the Poser icon at the bottom, to find the Configuration settings.) This will pop up a menu, and find LIBRARY_EMBEDDED_TYPE 0. Change the zero to a 1 and save the file. If your libraries in Poser 2014 stopped working, change LIBRARY_IS_AIR from 1 to 0.
Finally, open Poser and your libraries will populate. The only difference is that the Libraries palette may be in white.
Upgrade to a more recent version of Poser.
Poser 11 and Poser 12 are not reliant on Adobe Flash at all.
For a limited time, we have released Poser 11 from the vault for $99.99. In addition to fixing the Adobe Flash problem without you having to edit files, it also comes with over $900 in FREE downloadable content, gives users access to the functions that were formerly restricted to Poser Pro versions and introduces the SuperFly Render engine based on Cycles. Get Poser 11 here.
Or you could jump versions to Poser 12.
The newest version of Poser updates the SuperFly render engine based on Blender's Cycles 1.12. SuperFly's new Adaptive Sampling improves render speed and quality by detecting render noise and focusing on noisy areas. The new render engine gives improved compositing capabilities with its new shadow catcher objects and background transparency.
Poser 12 also adds support for Nvidia's raytracing hardware, Intel OIDN, an A.I. based image denoising system, a new post effects palette for denoise and more, and Python 3 scripting for improved security and stability. And it continues support for Firefly render engine and legacy content, La Femme and L'Homme, and more.
If you aren't sure, try the 21-day full feature, free trial. Download it here.
Options 1 and 2 do not work for users of Poser 7 through 9 were also affected. These users and any other affected users can fix the issue by installing a third-party library manager.
P3DO is a multimedia tool for viewing and managing your CG assets, 3D objects, 3D animations, and digital pictures with a simple, intuitive, thumb-nailed interface. It works in all versions of Poser along with other 3D program library managers.
For Poser users, the program acts as a Libraries browser, creating thumbnails, Runtime shortcuts, and colored directory nodes from internal and external runtimes. The browser displays your content in an Explorer-style window.
