Bot Framework composer not opening from within Power Virtual Agents web

Posted on by bikashb

All,

I have the bot framework composer v2.1.2 installed on my laptop (spec below)

Windows 10 Enterprise build 19041.1.amd64fre.vb_release.191206-1406 / OS Version: 10.0.19044

Processor: 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz

When I go from https://web.powerva.microsoft.com/ and click on "Open in Bot Framework Composer" , it just opens up the dialog of "Opening Bot Composer Framework" but nothing opens. The try again option does not work either and not sure where to use the link at.

I am able to open the bot composer individually but just that since it is not opening from within the PVA, I am not able to use it.

Any suggestions?

Thanks!

I’m also having the same issue although I’ve only just installed it so I’m not sure if this is something I’ve done wrong. I also installed Node JS as instructed on the Microsoft documentation.

It opens the composer and says ‘importing bot’ then nothing happens. The popup disappears and it just sits at the initial menu screen.

Any ideas anyone?

I believe I have found a solution (fix) to "composer not opening from within Power Virtual Agent"

Firstly I should confirm that I'm installing it for "all users" (C:\Program Files\...) with the System account (via SCCM).
But for trouble-shooting purposes I tried a per-user install, temporarily giving my account local admin privileges, else I would have trouble with AppLocker stopping it.

With the per-user install I tried the PVA website again and this time I was presented with an additional prompt to "always allow web.powerva.microsoft.com to open this type in the associated app" and to click Open. This had not appeared when I installed the all-users version, so it makes sense it couldn't be directed to the Composer app.

I did some searching and found that with the per-user installation, the association/link had been created in the registry HKEY_CLASSES_ROOT\bfcomposer and pointed to the application EXE file path within my Profile appdata area.

So I decided to export HKEY_CLASSES_ROOT\bfcomposer then simply edit the values to the path to "C:\Program Files\Bot Framework Composer\Bot Framework Composer.exe" "%1"

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\bfcomposer]
@="URL:Bot Framework Composer"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\bfcomposer\DefaultIcon]
@="C:\\Program Files\\Bot Framework Composer\\Bot Framework Composer.exe,1"
[HKEY_CLASSES_ROOT\bfcomposer\shell]
@=""
[HKEY_CLASSES_ROOT\bfcomposer\shell\open]
@=""
[HKEY_CLASSES_ROOT\bfcomposer\shell\open\command]
@="\"C:\\Program Files\\Bot Framework Composer\\Bot Framework Composer.exe\" \"%1\""

I completed a new "all users" installation then imported the registry values that were missing. I went to the website, tried the Open with Bot Framework Composer. I was prompted to "Always allow....", ticked the box, clicked Open and it worked! The project opened with the local Bot Framework Composer app (after some authentication prompts). Interestingly, it continues to show the window "We tried opening...on your computer" box but you can close/ignore it. Perhaps this always shows to give you the option to copy the link should you need it??

My "fix" for our app-deployment is to install the app (for all-users) and then post-installation add those registry values to complete the association. This is straight forward enough as we use PSADT.

For my issue I fixed it by turning off our internal VPN. It appears this was somehow blocking the importing function.
As soon as I did this I retried the ‘Open Bot Framework Composer’ option on the Topic menu and then I was prompted to save it as a new bot in the composer.
I would advise anyone having issues to ensure they have (as a minimum) NodeJs installed and turn off any VPNs they are using when interacting with the composer.

Just for reference, the whole process works fine for both our LAN and VPN-connected clients. With most of our clients working remotely now, it definitely has to work on VPN.
