CAN'T OPEN BOT FRAMEWORK COMPOSER V2.0

[victorlamana]

Hello! Title is self explanatory. I'm working on a bot on Power Virtual Agents and can't open Bot Framework Composer no matter what (It's stuck on "Starting server").

I followed the tutorial of installation on Framework Composer page and installed the SDK and the Bot Emulator, and they both seem to be working ( I can even open Framework Emulator). But when I try to open Framework Composer, be it by Virtual Agents or simply by clicking on it on the desktop, it always gets stuck on the "Starting server" message.

I tried without VPN, with VPN, disabled proxy and the results are always the same... I opened the bot on CMD and found the following error message on log ( I dont know how to fix it, but I think it is a good starting point nonetheless):

C:\Users\lamanv\AppData\Local\Programs\Bot Framework Composer>
(electron) The default value of app.allowRendererProcessReuse is deprecated, it is currently "false". It will change to be "true" in Electron 9. For more information please check electron/electron#18397

What should I do? Has anyone had a similar issue?

Any help is appreciated, thanks a lot!!!

Hi @victorlamana , thanks for reporting the issue. This error is due to some native dependencies not being able to load on your system. Can you give us a little more information on the environment you're using? Is this Windows 7/8/10?

Hello @taicchoumsft !!!! :)

I'm using Windows 10 Enterprise Build 1809

Is there something manual I can try to do to brute-force and open it?

Hi @victorlamana , can you try installing the latest vc_redist.x64.exe package from here, reboot, then try re-opening Composer again?

If you are also running an older version of Visual Studio (older than VS2019), can you update that and try again as well?

[victorlamana]

Hello, good morning @taicchoumsft. I'll try it later today and i'll report the results, thanks a lot

Installing vc_redist worked! Now I can open the program :)

Thanks @taicchoumsft !!!!!
