Update [1]: - Using Visual Studio Community 2015 - Update 3 Update [2] - Using Visual Studio Community 2017 - 15.4.2 does not make a difference. Update [3]: - Added visual image of what has changed and might cause this problem: ![219456-4-18-binaries-issue.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/f/7/1f74999fc9088de36912abbbdb26c266c4579715.png) ==== What: - Error about Modules not found or build with different engine version - Project is created from Blueprint (Empty Project) and added a C++ class to it. - Our team uses version control and I have excluded (.modules, .target and .pdb)-files from version control, since we did not need it for every change (only programmers have visual studio installed). When: - Starting up ProjectName.uproject with only Binaries/ProjectName.dll - **No .modules, .target or .pdb files** (also in Plugins folder which is not shown in example project). Expected: - To open uproject without asking to compile source project. ==== I have created an example project in how to reproduce this issue: - Clean (contains no additional .modules, .target or .pdb files, only .dll) - Clean\_with\_binaries\_modules\_target (contains .modules, .target and .pdb in Binaries folder) Tested this out in **4.16** , **4.17** and it didn’t gave me this message.

Hi! We have the same workflow and we also had a similar problem. We solved it, by adding UE4Editor.modules to Binaries folder in our project (to Binaries for Plugins folders too), after that our artists and designers succesfully run editor. * * * **Project/Binaries** ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/d/2/7d210dc903547379b5180077259dc5ee0bb480e3.png) **Plugins/Binaries** ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/7/b/17b928f6fd9ac789ae0dd92c4d21bf8fd8baec16.png) ---

Hello , That makes sense hence why I have found out when excluding all the files except .dll it reports the message. I am currently checking out with only .DLL & .modules included in our project and will get back when I know more (including CI-builds, Continue Integration builds). ---

Hey , So far this has been working. * * * Including **.modules** files in your binaries works. * * * Visual Studio does not modify .modules if the DLL is not missing, which is a plus for version control. I can continue get our 4.18 project to be stable again due new errors! Thanks y’all. ---

Hey , how would I go about this if I don’t have a “Binaries” folder? I was .git ignoring it so it wasn’t in my project folder. I tried not ignoring it and rebuilding my project but the “Binaries” folder still doesn’t come up. What should I do? Thanks so much for your answers. ---

go to the folder and “git add filename.ext -f” Would suggest making sure you git ignore the pdb files, or are happy with having them in git (use lfs).
