Hi my friend, without admin privileges on some pcs the app can t save downloaded files

Hi my friend, don t worry about me, i am here to help!

yeah maibe the driver is problematic, lately NVIDIA GameReady drivers haven't been very stable and have a number of issues; you should try the ‘Studio’ drivers, which are much more stable.

Have you also tried setting the multithreading value to different numbers (2 or 4) with RealESRGANx4 ?

This happens with all videos? or just one in particular?

Hi my friend! 

That's a beast of a setup! A 5090 with 96GB RAM should handle almost anything, so let's figure out why it's tripping.

To help me investigate the crashes, could you please provide your full specs and QualityScaler settings? Specifically:

• OS: (e.g., Windows 10/11)
• CPU: ?
• GPU Driver Version: (important for the 5000 series)
• AI Model used: (RealESRGANx4 or others?)

• Input File Type: (Video or Image?)

In the meantime, testing with AI Multithreading OFF is a great first step to see if it's a synchronization issue. 

Looking forward to your details!

Hi my friend, 

this happens with specific link? or specific files?

Hi my friend,

Unfortunately, yes, RealESRGANx4 has been temporarily removed in version 2026.1 because it is not properly supported in the current version of the AI engine (required for the two new models introduced).

It will be reintroduced 100% with 2026.2 along with the AI engine update (expected in March 2026).

In the meantime, I recommend using BSRGANx4 (very similar to RealESRGANx4 in terms of quality)

I apologize for the inconvenience.

Hi my friend, 

It has always been this way, it only happens with those two antivirus (which I am not personally familiar with).

I also contacted the two companies to resolve this issue, but they did not respond.

Hi my friend, 

from version 4.6

Administrator Permissions Required 🔒

⊡ QualityScaler now requires administrator permissions to work

⊡ This change fixes a bug that was preventing access to the DirectML library on some PCs

⊡ Without access to DirectML, the GPU couldn't be used correctly for AI upscaling

Hi my friend, 

This occurs when the image exceeds the memory limit selected in the GPU VRAM widget.

This value is set to 4 by default. 

You can increase it if your GPU has more than 4 GB of RAM, and the problem will disappear

Honestly, it doesn't seem like an ARM compatibility issue.

Did you extract QualityScaler.exe from the zip file? Maybe extract it to your desktop.

Are you running the app as an administrator? (Right-click > Run as administrator)

Hi my friend, 

never tested compatibility with Windows on ARM, what kind of trouble?

The error happens only with images?

Hi my friend, 

In what situation does the app crash? When starting up or while downloading?

Have you tried running it as an administrator?

Hi my friend,

i will give a look, thank you!

Thanks to you my friend :)

Hi my friend, 

sorry for the problem, i will send a report to Microsoft, there are no trojan in the zip.

I scanned the .zip and the .exe with VirusTotal finding no problem :(

Hi my friend, 

I'll take a look at this issue, thank you very much :D

Hi my friend :D
Thank you!

Nvidia 1660? 

No specific advice other than the general tips provided in the app by clicking on the blue “?” buttons.

For videos, use “RealESR_Gx4” and “RealESR_Animex4,” which are the fastest models. For images, feel free to use whichever model you prefer.

thanks to you my friend :D

Hi my friend, 

in the same directory you downloaded FapelloDownloader.exe

send the me the link and i ll check :)

Hi my friend, sometimes the website deletes some files without update the file counter.

So if a page has 200 files but in reality there are only 150 files, the app only download 150 files 

Hi my friend, thank you ❤

the image input feature is currently in working progress

however with limitations on the resolution of the images: the 2 input images must be perfectly equal in resolution otherwise RIFE goes into error :(

Hi my friend,

do you get a video encoding error? i.e., the final stage?

you can try running the app as administrator (right click on QulityScaler.exe > run as administrator)

in any case contact me on the telegram group so I can help you better

Hi my friend,

good thing you don't have connection problems! :D 

with 4.0 I will revise all the code and solve all these little problems, thank you very much :)

Hi my friend, this can be done without problem :)

Hi my friend,

Then QualityScaler and RealScaler are pretty much the same, but QualityScaler has support for more AI and is updated more often.

Initially (about 3 years ago) I created 2 different projects because the individual apps weighed a lot and I had a lot of difficulty encapsulating all the AIs in one project. As I progressed, however, I was able to make the apps much smaller, so splitting was no longer necessary, but since I had already put both apps up for sale I decided to make QualityScaler the main app and RealScaler the secondary app but still support both out of respect for those who had purchased both.

I was also a fan of FlowFrameshaha, but just because it didn't update the app anymore I decided to make my own, constantly updated with different improvements.

If you are interested in a FlowFrames alternative, there is my FluidFrames app (https://jangystudio.itch.io/fluidframesrife)

Hi my friend,

the version 4.0 is ready, i am waiting for Microsoft, Avast, Avg certifications :)

definitely ready in 2 weeks

Hi  my friend, you are right, checking the files already done could also be a solution.

unfortunately I am away from home for work at this time and I am without my PC and I don't know when I will be able to work on it sorry :(

Hi my friend, 

i tested the app right now and it works, but sometimes fapello.com blocks the connection, but if you retry it will download again and finish maibe. 

In the next update i will fix this issue, thank you for the feedback :)

Hi my friend, have you tried different countries with VPNs? :)

Thank you my friend!

The version 4.0 will take a little more time because it will be a true major release, with improvements in all the features and especially a more elegant and clean interface (the current one has become a bit of a mess haha)

(I leave a small spoiler)

Hi my friend!

It works! awesome!

Thanks to you finally there will be hardware accelerated encoding on GPU, Nvidia, AMD and Intel specific (in addition to CPU encoding that I will leave for compatibility)

This also allows me to finally get rid of some dependencies and then have a lighter and more optimized app.

I thank you from the bottom of my heart :D

Hi my friend, thank you!

So if I understand correctly the frames.txt file contains the list of upscaled frames as a path to the file right?

Hi my friend,

I have tried for a long time to implement hardware acceleration of ffmpeg but without success unfortunately. The documentation is very poor.

Do you have any advice? Any guides I could follow?

From what I understand ffmpeg has to be compiled with hardware acceleration to do that, and they don't distribute .exe already precompiled this way :(

You are welcome my friend! :D

Hi my friend and thank you :D !

FluidFrames already has STOP&RESUME functionality,

if you press STOP during the frame generation of a video the app does not delete the frames generated up to that point and, restarting the process resumes from the interrupted point.

Obviously you should not delete the folder of files already generated, otherwise it will start over again.
Also changing some settings does not allow the process to resume, for example:

•  changing AI model,
• changing AI frame generation option
• changing Input Resolution %

 the settings must be the same to resume the process.

Hi my friend,

yes, I know this problem and I'm trying to break up the error messages so that the display is better.

You can't get a screen? does it always happen to you but you can still use the app?

Hi my friend

Thanks to you for the feedback :D

Hi my friend, 

this link doesn't seem to work properly for me either, I will investigate the problem.

Other links work without problems

Hy my friend, RealScaler 3.9 is the latest version.
