Did you install version 2.6.1 (the large blue button on our download page, or one of the daily builds?
Also, whichever you're using, does it also occur when you try the other?
The same behavior occurs with OpenShot-v2.6.1-dev-daily-8737-18bdad43-0fb4ab09-x86_64 I installed it following instructions in the process of reporting how I can't add project files with OpenShot-v2.6.1-x86_6 libopenshot.log openshot-qt.log

I'm pretty sure I ran the daily build as well, I certainly tried the official version 2.6.1. Unfortunately, I don't have access to the "offending" PC at the moment, so I could verify if I tested the daily build.
Hi, I'm experiencing the same problem. System Details: OpenShot Version: 2.6.1 Operating System: Windows 10 Pro
- Version 21H2

Set the display language of win 10 to English US (for example I had Romanian and so on, it didn't start). It worked for me width EN US!(for 30 computers)

My Windows language is English US, so that won't do the trick
Hi, had the same issue, found the solution.
It appears the issue is because Windows N does not include Microsoft Media Future pack by default.
I fixed the issue by following method 1 in following link: https://ugetfix.com/ask/how-to-fix-mfplat-dll-missing-on-windows-10/
You will probably have to find the correct version of the media pack by going to: https://support.microsoft.com/en-us/topic/media-feature-pack-list-for-windows-n-editions-c1c6fffa-d052-8338-7a79-a4bb980a700a
Thx a lot @Frari489, the media future pack was also missing in my case (W11): Please find it here
Cheers
@tkazik Could you share some details about your computer setup like your processor, and the OpenShot versions involved? (I'd ask what OS, but I assume from your comment you're using Windows 11.3)
I'd love to track this issue down, and see if we can include those media packs in openshot's installer.
@JacksonRG sorry for the delay:
- MS Windows Version 21H2
- AMD Ryzen 7 PRO 5850U with Radeon Graphics
- OpenShot version 2.6.1
Hope this helps.
@tkazik Unfortunately I don't have an N edition of windows to test on, but several users have reported that
https://support.microsoft.com/en-us/windows/media-feature-pack-for-windows-n-8622b390-4ce6-43c9-9b42-549e5328e407
support page from microsoft explains that N editions are missing the media futures pack, which has to be manually enabled to allow windows to access several types of media.
If that helps you, I can work on adding a special error message to openshot which directs people to install that media pack.

If you can detect that, yes, please. This will certainly be appreciated by someone running into the same surprise :)
In my installation: v.2.6.1, Win10 Pro 21H2 the issue seems to be related to transitions translation.
Source files of error: C:\Program Files\OpenShot Video Editor\windows\models\transition_model.py
code lines:
if suffix_number:
trans_name = trans_name.replace(suffix_number, "%s")
trans_name = self.app._tr(trans_name) % suffix_number
else:
trans_name = self.app._tr(trans_name)
More exactly, Luminous boxes transition models failed to translate. In my case (romanian language) Luminous boxes %s translates to Cutii luminoase %. Please note the missing s. So, with this translation, the following code block which should replace the %s with the suffix_number will fail.
Putting the affected code into a try: except: block solved the issue and the launch of OpenShot completed successfully.
try:
if suffix_number:
trans_name = trans_name.replace(suffix_number, "%s")
trans_name = self.app._tr(trans_name) % suffix_number
else:
trans_name = self.app._tr(trans_name)
except:
log.info("Failed to translate {}".format(trans_name.replace("%s", suffix_number)))
Luminous boxes transitions remains untranslated, which is not a big deal.
@slimbyte Thanks for your debugging on this issue. What language are you running openshot in? We have automatic tests of our translation code, so this may help us find a gap in that testing.
@JacksonRG I was running OpenShot in Romanian language.

Same issue with romanian language, thank you for the work around!.
Windows 11 PRO
Please try the latest DEV Daily Build of v3.0.0 and confirm either way.
my fix was
On Windows 10 N: Select Start, then select Settings > Apps > Apps and Features > Optional features > Add a feature. Find the Media Feature Pack in the list of available optional features.
On Windows 11 N: Select Start, then select Settings > Apps > Optional features. Select View features next to Add an optional feature, and then select the Media Feature Pack in the list of available optional features.
