vc_redist.x64.exe установлено. ОС: Win7x64

There is a description of a similar problem here: https://github.com/ultralight-ux/ultralight/issues/50

Thanks for the report and the link!

Please, test this build. alfis_v0.3.5_issue7_test.zip

Now the message about the missing library is not displayed, but the application still does not start. It just ends silently.

Here is what is contained in the windows log:

Although, the application ends with an error in the log, but the file blockchain.db appeared in the directory with the program. This is a SQLite database, there is a description of the structure, but there is no data.

Do you have alfis.toml in that directory as well? What if you try to run it with Administrator privileges?

Yes, alfis.toml is in the program directory. I tried to run the application with administrator rights - this did not affect the behavior. The same appcrash.

I overcame my laziness, installed mingw and tried to compile the binaries myself. At the very end, the following message was displayed:

...

    Finished dev [optimized + debuginfo] target(s) in 10m 01s

The binary in the target\debug folder has been created, but it won't start. The same message is displayed as in my first post :)

Okay, I've fixed a warning. But I don't really know what the second error is and how to fix it. The original one is understandable - those functions to work with HighDPI screens appeared only in Windows 8.1, so you have a very old OS.

I understand that this OS is no longer supported, but I still work in it. I don't like Windows versions greather than 7 :) Just like many other users... And my main OS on my home PC is Linux...

Well, I managed to run Alfis on windows 7 x64.

git pull origin
cargo build

Now the build went through without any warnings.

Next, I downloaded api-ms-win-shcore-scaling-l1-1-1.dll from this link, copied it to the directory where the alfis binary is located and ... It started :)

So, if you do not intend to further investigate and support the work of Alfis on Windows 7, I think this issue can be closed.

Maybe the simplest solution would be to add a flag for compiling without High DPI screens support )

I can say that he uses non-MSDN Windows 7 image, something like "by Vasya" castrated system. In that case only clean install of system without such changes would fix issue. I saw such problems with i2pd users, the reason was always such systems with cut out components.

I use Windows 7 Professional SP1. Nothing was specially cut out of it.

Hah, so that functional available since 8.1? In that case only upgrading can help I think.

Haha, found it: https://github.com/Revertron/Alfis/blob/cb8b207f341cab58d750c2d96f215c78314c1270/Cargo.toml#L41 https://github.com/Revertron/Alfis/blob/cb8b207f341cab58d750c2d96f215c78314c1270/src/main.rs#L33-L34

So maybe here any other solutions to work on old system without that API?

@r4sas, that test build above is built without these lines :)

That's with default IE 11. Webview appears, JS error shown, and after that error in console at last line.

Removing lines from https://github.com/Revertron/Alfis/issues/7#issuecomment-810277389 and latest fix from https://github.com/Revertron/Alfis/commit/11bc887fbb5051f6ad30c5d5f234185cf53ea914 make able to start Alfis on Win 7.

With 0.3.8 api-ms-win-shcore-scaling-l1-1-1.dll still has to be manually applied.
