cant use built model

[reza-shahriari]

Question

can you please explain step-by-step how to use it?

I have cloned your repo and then built it with vs 2022 now I cant use blocks nor plugin!. both of them showing this error: Severity Code Description Project File Line Suppression State Error C1900 Il mismatch between 'P1' version '20210224' and 'P2' version '20210202' MyProject7 C:\Users\iust\Documents\Unreal Projects\MyProject7\Intermediate\ProjectFiles\EXEC
what should i do ?

Using:

windows10, last version of colosseum, python is installed by vs 2022,unreal 5.2

Strangely having this exact issue right now, using unreal 5.2.1. Tried VS2022 and 2019 with no luck...

@reza-shahriari Do you have multiple versions of Visual Studio installed? If so, delete the oldest one and ensure only VS 2022 is installed

You also need to do a clean on Blocks (delete the Intermedate and Binaries folder), then build again.

This is because when you switch UE versions, you have to switch VS versions, which cause conflicts with the build process. This is an Unreal Engine issue that I still have not found a way to automate.

@xxEoD2242 Thanks for answering fast! I had vs 2015 installed and I deleted it but steal seeing the error :( Severity Code Description Project File Line Suppression State Error C1900 Il mismatch between 'P1' version '20210224' and 'P2' version '20210202' Blocks D:\AirSim-Unreal\New folder\Colosseum\Unreal\Environments\Blocks\Intermediate\ProjectFiles\EXEC 1
would you help me please?

i have airsim and unreal 4.27 installed. is it any problem with it?

[xxEoD2242]

You need to install VS 2022 and then remove those folders I mentioned.

That shouldn't be an issue as long as you are in Colosseum

[reza-shahriari]

Unfortunately, we are super busy with our new product launch this week.

If I have time next week, we could possibly meet. In the meantime, I would recommend getting on Discord and asking your question there.

[reza-shahriari]

[xxEoD2242]

[reza-shahriari]

Thanks a lot 🙏🙏 I am seeing this when I want to join discord

May be link should be updated

[ides2327]

Just fixed this problem for myself. I had VS Build Tools 2019 while my VS Community was 2022. Maybe try checking your version of build tools.

[reza-shahriari]

@ides2327 i'll check it thanks for helping

[reza-shahriari]

@ides2327 i cant find any other version of Vs in my pc........ every where i thought it may b another version:

as you can see no other version... or may be i am wrong and i have to see some where else? i also checked the path and it was not any vs in it

[ides2327]

Check the Visual Studio Installer, you may have something like this:

Having the same issue with a clean (and only) install of VS 2022 with UE 5.2.1 and Colosseum 2.1.0.

Already set the VS 2022 as a default source editor in UE.

Tried the last commit, 1d9b330, as an addition to the 2.1.0 release.

Deleting the Intermedate and Binaries folders then building again did not solve the issue.

Solved my issue.

I thought I needed to download the exact Windows SDK version mentioned in the docs, turns out I need to get the latest one listed in the VSC installation list.

Make sure to uninstall all other versions of VS, even the versions of 2022 (17.7, 17.6 etc.). Best way to do it is completely uninstalling the all VS related programs including the installer, as mentioned above by others.

Then do a clean installation after restarting your system. During the installation, just to be safe, select all Microsoft SDK versions, select the latest .NET Framework.

Might also help; Start the VS with admin rights. To do that with the sln files, you need to right click the "devenv.exe" to open the troubleshoot compatibility screen then select "this program requires additional permissions".

ill try it ASAP thanks for the comment
