thanks for the detailed report. i have not encountered this issue, or seen any reports of it so far. and only have little windows knowledge :)

can you try a different folder? maybe (pure guess) windows doesn't like dll's in Downloads folder?

otherwise hope someone else knows what the issue is.

[boudann]

Yeah, it's a weird issue. I had this running fine on a different computer. Tried on this new one, no go. I thought the same thing about trying in another folder, but didn't work. Tried running as administrator, tried powershell vs cmd prompt, tried unzipping w/ 7zip instead of the built in Windows archiver. No luck. This is a brand new fresh install of Win10. I'll keep trying stuff. thanks, Brian

When you launch the .exe from a new folder it should insert the simconnect.dll file into that folder. I am guessing that part isnt happening?

I haven't learned enough about the code to know where that .dll is coming from.

If you copy the file from the PC where its working, and place it in the same folder as the .exe on your new machine, i assume it'll work as a workaround.

Unfortunately I'm having the same issue after my brand new computer format.

panic: Failed to load D:\MSFS\Community-- vfrmap-win64-v0.0.7\SimConnect.dll: The specified module could not be found.

I've been trying to replicate this to help find a solution, but i cant seem to replicate it.

Can anyone check their event Logs and see if Windows is blocking the simconnect.dll file from being tossed into the folder with the .exe?

[lian]

@Bi0force1 doesn't his first comment show that dll was written 2 File(s) ?

thank you for helping to solve this!!

[boudann]

The dll file gets written into the directory the first time vfrmap.exe is executed. I showed this in my initial comment.

I verified AV is not quarantining and same issue persists w/ all default Windows Defender junk turned off.

[Bi0force1]

Lets look at 2 things.

1. Right click on simconnect.dll, on the General tab is there a warning "this program is blocked"? If so, is there a unblock button that you can click.

2. In the same properties file, go to Security tab, do you have permissions checked for: Full control, Modify, Read and Execute, Read, and Write?

[zazaboeing]

Hi!
1 - There's no such warning, and I've made sure to have ownership of the file, no windows defender, firewall or antivirus at all is interfering, those are all turned off.
2 - All those are checked!

Tried many different settings now, every compatibility test and it's definitely not working. It opens momentarily (for a very brief milisecond) the command prompt screen and closes silently. No windows event viewer message also.

Hi,
I am having the exact same issue (see post one) on a brand new HP-Omen W10.
(Other tan that - this is the ONE tool vor MSFS that I was hoping for)

[erichump]

You need the "Microsoft Visual C++ Redistributable for Visual Studio 2015". SimConnect.dll is compiled to link dynamically to the VC runtime.

[msfsuser]

Yes, that worked. Just had to run the latest vc_redist.x64.exe (not sure about posting links here) which added the 2015 files. Those are apparently missing on new systems.
Thanks!!

[lian]

@erichump awesome, thank you for debugging this! iirc steam auto installed vc_redist.x64.exe on install for me.

You need the "Microsoft Visual C++ Redistributable for Visual Studio 2015". SimConnect.dll is compiled to link dynamically to the VC runtime.

i've got the same issue but vc_redist.x64 is already installed. It's a fresh windows installation do we have some ideas for me

[reanorius]

Can someone fix vfrmap.exe? It stopped working after the yesterday's MSFS 2024 update. I am ready to pay 50$ if you can fix it and then let me know how to fix it when the MSFS 2024 updates again.
