Hi
@strezoiu,
Sorry for the delayed reply.
So based on your on your error message, what is happening is that it looks as though you are packaging a win64 app, is this correct? (You specified your system and I just want to verify that you are packing win64 as well.

)
We will work on reproducing this issue on our end to determine why this is happening and have a fix as soon as possible.
In the case you prefer not to wait: This error message is from UE4 attempting to build the Substance plugin at package time and it fails to do so as you don't have the tools installed. (This is the result of missing files from the plugin installation which is what we will be investigating.)
Error: No 32-bit compiler toolchain found
An immediate solution would be to install one of the free versions of Visual Studio that has VC++ and package once more. This will rebuild the plugin and (in theory) work as intended.
As mentioned, we will work on getting this fixed and I will post an update here when we have an update.
If you could send me any of the following, it would help greatly and speed the process up:
- The version of UE4 that you are using
- ZIP file of the installed plugin (Only needed if the plugin was not acquired through the UE4 Marketplace)
Sorry again for such a late reply!
Cheers!
