Re: NVDA Installation failed

Felix G.

this one was gone for some time but it has a way of reappearing. If
I'm not mistaken, it's a string which got translated when it shouldn't
have been.

Hi Kostadin,

Are you sure it's the same bug? If it was and if it has been there five years, installing NVDA 2019.1 shouldn't have worked either. But I was able to install that version successfully.

Hello Quentin,

If I'm not mistaking, this is a known bug in NVDA. I've reported this almost 5 years ago and it still occurs. Here is the bug: NVDA installation may fail with an error if system UI language and language for non-unicode programs don't match · Issue #5166.

Best wishes,

Hi Sandra,

Thanks for following up, I appreciate the clarification.

Setting my system language to German, I can replicate this. We'll look into it.

Hi Quentin,

You wrote:

When you originally went to install, did you get the UAC prompt from Windows itself about installing the program? You get that for any program you install, but sometimes it pops up and doesn't get focus so you aren't alerted to it and even visually it's not obvious. If you don't answer Yes to the UAC prompt within about 20 seconds, it times out and denies the program from installing.

Yes, I did see it, but the UAC prompt isn't the problem, I always answer Yes using the alt Y or in my case alt+j shortcut (German windows), and the installation continues. I don't wait for 20 seconds for something to happen.

The only other thing I was thinking was if you had controlled folder access set, it will install NVDA but not create the desktop shortcut. If that was the issue though, it wouldn't have worked any better with NVDA 2019.1 than 2019.3.

No, I don't have controlled folder access set. I checked this when it didn't work, because I knew it could be a problem. No, it's not active.

I do think there is a problem with the installation of 2019.3 though, because a lady on the German NVDA list reported the same problem. She's a very competent computer user and I'm sure she, too, knows how to deal with UAC. Maybe it doesn't affect systems where English is the default language... And maybe it wasn't reported much, because many people using NVDA 2019.3 will have updated an older version and won't have encountered this issue, because the shortcut and start menu entries had already been created by a previous installation of an older version of NVDA...

I, however, attempted a fresh install on a new machine.

Hi Felix,

Thanks for your help. Unfortunately setting the NVDA language to English
didn't help. The failed installation not only faild to create the
desktop shortcut, but also didn't create NVDA entries in the start menu.
I installed NVDA 2019.1 first and then updated to 2019.3.1, that did the

Hello Sandra,
the installation failed because NVDA was unable to create its desktop
shortcut, for reasons I cannot begin to guess. I can think of two
1. Install without creating a desktop shortcut, then create one manually.
2. Sometimes, switching the NVDA language to English before installing
fixes this problem. If you feel comfortable doing this, it may be the
cleaner option.
Hope this helps,

I'm trying to install NVDA on a new machine running Windows 10 pro 1909.

I'm running the installation file as administrator. I'm getting the message that installing NVDA has failed.

Please also see the log included below.

Does anyone know what the problem might be and how to solve it??
