I'm on Windows 8.1, with VC++ Runtime installed (ver. 2005 x86, 2005 x64, 2008 x64, 2015 x86, 2015 x64). Does the latest Falkon require VC++ runtime 2008 32-bit, or a newer version of VC++?

Visual C runtime 2013 x86 and more

It turns out it needs version 12, 32-bit. I'll do a repack as Rev 2 with it included. I couldn't tell before as I don't currently have a working Windows 8 virtual machine and Falkon crashes on Win7 for me.

EDIT: It needs another one in addition to it, likely 2015 or 2017, as it is missing api-ms-win-crt-heap-l1-1-0.dll. I'm going to check tomorrow. Note that the local version of Falkon doesn't have any checks, so users aren't able to run it without manually figuring out what they need and installing it. I tried installing both and it crashed with a Qt error on Windows 8. Still working on it.

Sometimes, the impossible can become possible, if you're awesome!

Thanks for that.

Thanks for that.
It seems that similar problem had been reported at https://www.falkon.org/2019/03/19/falkon-310-released/#disqus_thread two months ago, without further technical details, but the symptom is identical. Since even the installation version has the same problem, the original developer of Falkon should also be responsible for it I think. Maybe you can report this issue to https://www.falkon.org/development/ ?

Process loads and immediately terminates with no message / error

I think what I'm experiencing is related. On Win7, trying to run Falkon 3.1 causes the process to load and immediately terminate. No message or error is produced.

I tried upgrading 3.0 to 3.1 as well as a fresh install. Both have the same result.

Install KB2999226?

Have you installed this hotfix? Falcon apparently requires this in addition to the Visual C++ 2013 32-bit libraries. I can include the libraries but I can't include the hotfix.

Fixed in Rev 2

This is fixed in Falkon Portable 3.1.0 Rev 2. If you're still having an issue, ensure you have the necessary hotfix and OpenGL driver as indicated in the app notes: https://portableapps.com/apps/internet/falkon-portable#app-notes
