I have a doubt in the following documentation Rebuilding zoom node file If you are building your own version of the Electron SDK, you will need to follow these steps: 1. Download the protobuf 3.4.0 source file and rename the src folder to protobuf\_src. 2. Copy the src folder into the lib/node\_add\_on folder. 3. Run the build\_nodeaddon script: What i did is i have downloaded the source code(zip) file of protobuf from this link [Release Protocol Buffers v3.4.0 · protocolbuffers/protobuf · GitHub](https://github.com/protocolbuffers/protobuf/releases/tag/v3.4.0). Extracted it and copy the src folder and renamed it to protobuf\_src and placed this protobuf\_src inside lib/node\_add\_on Now when I run “\>run\_demo\_win.bat” the following error occurs- "zoom-sdk-electron-5.7.1.643\lib\node\_add\_on\electron\_sdk.pb.h (10,10): fatal error C1083: Cannot open include file: ‘google/protobuf/port\_def.inc’: No such file or directory [c:\*\*\*\zoom-sdk-electron-5.7.1.643\build\zoomsdk.vcxproj] Please help ---

I had the same issue, you have to use a recent version of protobuf(\>3.17), _port\_def.inc_ doesn’t exist on version 3.4.0. Seems that the Zoom documentation is outdated… ---

But I am seeing another error: ```auto fatal error C1189: #error: This file was generated by an older version of protoc which is path\to\zoom-demo\zoom-sdk-electron-5.7.1.643\build\zoomsdk.vcxproj ``` Would appreciate if you can solve this issue. ---

the correct version is GOOGLE\_PROTOBUF\_VERSION 3013000 [https://github.com/protocolbuffers/protobuf/archive/refs/heads/3.13.x.zip](https://github.com/protocolbuffers/protobuf/archive/refs/heads/3.13.x.zip) is hidden in .\lib\node\_add\_on\electron\_sdk.pb.h with this the build works fine ! ---
