Can't open Premiere Pro 2025 after update

Hi, I have the same issue for Windows 11. I did everything; nothing changed. Adobe Premiere (25.2.3 and past versions) are still not launching. The other versions as well. I'm getting 'bad INDEX offset array' pop up.

Just 24 versions are working. Is there any current development regarding the issue?

I see, thank you. From what I can find online for Adobe on Mac, I don't think it is a requirement, but a recommendation. Anyways, for now it lives on my internal drive then.

Well, now that you got it to run, you don't need the cleaner, unless you want to start again clean. 

I can only speak from a Windows perspective, but that's pretty much a no-no trying to install a program on an external drive. I've been on a quest now for a few years to remove as much as possible from the C: drive, except program installations. I find it much easier to manage, and when I want to put a new version of Windows on (very soon now) just the programs need to be reinstalled (which I keep quite organized) and all the data and other files are there. Though I'm running 4 m.2 drive currently, they are all 'internal' but not the boot drive.

Glad it's at least working for no on the internal drive, and I do think Adobe has that as a requirement.

Yes, thank you. I had a look at it but did not yet find the time to go through all the steps. Should be able to do it later tonight or tomorrow.

Plus after you uninstall you can run the Adobe Cleaner, which I linked yesterday, did you have a chance to look at that?

Thank you @MyerPj @Rach McIntire  - I have now reinstalled to the internal drive and it works from there.

My question now would be: What do I need to do to make PP run from an external drive? I try to keep as much internal drive space free as possible.

Sorry, I remember that from yesterday now. That you were installing on an external drive. I'm with @Rach McIntire , try installing it on the internal drive, and do make plenty of room for it, and let's see how that goes.

Hi @Sebastian31633726m8lx,
When you click on the icon to open Premiere, is it on your SSD, in the Dock, or on the Desktop? Have you tried installing Premiere on your internal HD to see if that works? It would be helpful to narrow down if that is somehow part of the problem after the updates.

Thank you for your response @MyerPj . Yes, that's what I assumed - but also what I don't understand. I used PP 24 until last week without any problems. What has changed since are two things:

1. I updated to the current macOS 15.3.2

2. I deinstalled all Adobe apps on my internal drive and moved them to an external SSD (all other Adobe apps work just fine from there)

I appreciate any input. Here are the specifics again:

Workflow details: Tried opening the application from the external SSD, but it crashes immediately
