win32 API error 126 - and then I can't see the Library module ?

[simons21510170]

When launching LR I get a win32 API error 126 and after loading I can't see the library module.

I have installed adobe premiere elements 14 and have tried to delete it with no luck.

I have also tries to reinstall LR without any effect.

Some forums suggests that it has to do with an ATI graphics card but I have NVIDIA and I have checked that I have the latest driver as well.

Any suggestions would be appreciated

Hi simons21510170

Which version of Lightroom are you using?

Which operating system are you using?

Have you tried to uninstall and reinstall your Nvidia display adapter drivers?

Hi,

I have tried reinstalling Nvidia drivers with no luck.

I'm attaching the second message screen I get when starting LR. So the one above comes first and then this:

Any other suggestions ?

[Mrinmay Majhi]

Do you remember any changes which you made started the issue?

Have you installed any plugins for Lightroom?

[simons21510170]

I installed Premiere Elements 14 and there was an automatic update on acrobat reader.

I have uninstalled LR several times but I have installed Jeffrey's "export to picasaweb" lightroom plugin .

Where would I find that when I have uninstalled ?

Was there a resolution to this issue? I am having the exact same issue after installing the latest lightroom cc update, there was a windows 10 update at the same time on my pc.

I am also struggling with this issue with a brand new windows 10 and lightroom install.  Anyone figure out how to resolve this yet?

I had the same problem. Reinstalling Visual C++ 2010 both x86 and x64 did the trick.

Download Microsoft Visual C++ 2010 Redistributable Package (x64) from Official Microsoft Download Ce...

Fixed it for me too, after a Windows 10 update around 2/13/2018 broke Lightroom in the above described way.  Had to uninstall Visual C++ 2010 x86 & x64 and then reinstall without rebooting in between.  I tried it with a reboot and the broken version came back by itself.

It works! Thanks a lot

The link is not working anymore in 2025, however, I found this link instead. Installed it, and my LR works:

This worked. Thank you

I'm using windows 10, just uninstalled and reinstalled the latest LR cloud and i still get this message.

According to everything i've read, it says to uninstall and reinstall this MV C++ 2010 redistributable package, but i have so many.

Please help! The myportfolio website only works with this LR and not the desktop one.

I do not have an answer for the Error message.

Posting a screen-clip from Lightroom-Classic might help others with an answer.

only works with this LR and not the desktop one.

I do know that I can update my Portfolio web site without needing Lightroom (Cloudy) installed (on my desktop Windows machine).

I have Collections in Lightroom-Classic that are synced to the Cloud, I 'Sign in' to the Portfolio website (link below), and then add 'albums' (Collections) or change the design of my site.

Adobe should fix it...vs us hunting for a solution, as so many of us have the same problem.

This worked for me as well but can a PC expert of some sort tell me why it actually did? Like what exactly is downloading those programs for? Curious
