Can't Install v4.0.0

I can’t Install Video AI v4.0.0. I am getting this error

image

with v3.5.3 it worked fine , so with the Beta of v4. I upscale and use the tool without an issue. I anyway use my GPU mostly.
I am sure that v4 will also upscale my videos just fine. could you guys lift that limitation or replace this with a dialogue option (Continue YES/NO) for the user to choose?

Hi, which CPU are you using?

According to his profile, he is using Intel i7 4930k ( Ivy Bridge)

If it is that CPU, unfortunately it does not support AVX2 instructions.

I’ll come back to this post tomorrow when I have more information on which functions of the app now require AVX2 and if it would be possible to keep supporting the 4930k @Akila

Yes it is the Ivy Bridge. bear in mind that the Beta v4 worked on my machine without an issue (apart from the known UI bugs at the time)

I have the same issue (3770K, which was the fastest of the Ivy Bridges back in the day), but use my RTX2060 to do all the AI work and all v3 versions have worked fine…

Mines is Ivy Bridge-E which is the on the LGA 2011, quad channel (Xeon CPU).
the 3770 is the mainstream dual channel LGA 1155.

Anyway as a temporary workaround, I manually extracted the MSI installer (using UniExtract ) and copied the files manually upgrading to v4. so far it is working fine.

{SourceDir}\PFiles\Topaz Labs LLC\Topaz Video AI -> C:\Program Files\Topaz Labs LLC\Topaz Video AI
{SourceDir}\Topaz Labs LLC\Topaz Video AI -> %programdata%\Topaz Labs LLC\Topaz Video AI
{SourceDir}\System64 -> I believe it should go to System32 and/or SysWOW64, 
but I wasn't sure so I left those alone

hopefully they will remove this restriction from the MSI installer itself.

And I was disappointed that I needed to install Windows 10 (Back when I was on Windows 7 and installing VEAI 2). This would be so much harder to accommodate.

Posts in the 4.0 release thread don’t look promising, alas… I do wonder if you need AVX2 if you are doing all the AI on a graphics card (which I assume you , like me, are)?

I have no idea, in my settings it is set to GPU. what happiness behind the scene I can’t comment.
all I can say that v4 works on my machine and so far i noticed no issues

All models except maybe Gaia are very CPU heavy even when set to use the GPU. My guess is AVX2 is only used in the newest model Nyx 2. It could even be that they are working on a model that needs it, but is not released yet. There might be something in the timeline that uses it, but I think those that bypassed that restriction in the installer would have had issues with that by now.

Nyx v2 worked for me, wasn’t so happy with the results (compared to Nyx v1), but it finished the process.
the Question is AVX2 needed for performance or for actual functionality?

I agree. Nyx 2 needs fixed. I have a whole detailed bug report on it.

I don’t know much about AVX 2. AVX is a section of the CPU that preforms heavy calculations. AVX 2 doubles the size of instructions that can be sent to that part of the CPU. I think CPUs can still do those calculations without AVX, but it’s faster with it. I doubt fallback is automatic. That probably has to be programmed in.

Love to see it.

I am debating on Using an AVX Emulator if i see that things don’t work well. But I’ll leave it as last resort. as of now things are working.

Please just back the support of CPUs without AVX2 !!!
