Hello, I downloaded and installed the following from the Wago Download Center. - CodeSys 3.5.21.50 - WAGO\_BC100\_Device\_Support\_Package\_1.0.5.9\_171993.package - WAGO\_CODESYS\_Download\_Server\_1.0.1.0.package - WAGO\_Devices\_and\_Libraries\_2.0.8.9.package - WAGO\_SolutionBuilder\_Plugin\_2.4.2.0.package When I open a new project for the 750-8212 (FW30) in Codesys and compile it while it’s empty, there are no issues. However, when I add the DALI library, I get error c0138. I haven’t been able to resolve this issue at all. I’m hoping for your help. ![1](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/b/bc3b63684a05099846e81aa61eda7c207e88e850.png) ![2](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/2/26c09b7d75a5388f0809098fddfd2d65c330b298.png) ![3](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/5/51644ec4b49d304930d17904d8209bdb5ee60f21.png) ![4](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/f/f03d12adf91c85a7c46fd721cdacd12911e07692.png) ![5](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/c/cdcc78fb15f0e7a281cd9cb6b60371b0b4bc0456.png) ---

I installed version 3.5.19.70. I added the DALI library. It didn’t give any errors. Now, I’m going to uninstall version 21.50 and reinstall it. I’ll tell it to use the settings from version 19.70 at startup. Let’s see what happens. ![2](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/1/185c82b31a58071be9ff2add5390ea4da66cf957.jpeg) ---

I tried in my version of codesys 3.5 SP21 patch 5 and i get no errors. Have you done a clean all? ---

After uninstalling the program, I deleted and cleaned up all CodeSys-related files (appdata, program files, ets) and registry entries. I restarted the computer and reinstalled CodeSys 3.5.21.50. When I added the DALI library and ran a rebuild, I encountered the same error again. ---

Try to make a new project with the empty project template. I always use this one. ---

It throws an error in all versions: 21.10, 21.30, and 21.50. However, it does not throw an error in version 19.70. (The installations are the same, the method is the same; the error occurs after adding the DALI library to either a blank project or a standard project) Yes, it throws the same error even when I open a blank project. I think it might be conflicting with my computer’s CPU, graphics card, or Windows version.

I don’t know if Windows Home is supported by CODESYS. Please check the software’s requirements.

I installed Codesys 3.5.21.50 on another clean computer that had been reformatted and had Windows 11 Pro installed. I added the DALI library. Unfortunately, it still gave the same error. ---

Hello, When you look at the library manager, your WagoAppDALI have a underline, can you open the + on the left of the library name to see if there not another library missing somewhere ? You can also check in the Placeholder if there is not a Wago\*\*\*\* library that is empty. ---

Yes, I know. However, the error is caused by the VersionHistory file in the DALI library. Unfortunately, it still gave the same error. ![image](https://us1.discourse-cdn.com/flex016/uploads/wago/original/2X/c/c5766d1c4e5177e78161e4fa4daf4b379fc287f4.jpeg) ---

Just a thought, but is your device up to date? I mean, does the library version match the device description in your project?
