Latest 1.9 does not work with 2018.2.2 - BadImageFormatException

[acknickulous]

Due to my problems building with Playmaker in 2018.3, I rolled my project back to 2018.2.20f1. But the latest version of Playmaker 1.9 does not work with this version. I tried fully deleting Playmaker and re-installing to no avail: I get a constant flow of errors in the console and none of the editor windows work (the third error repeats forever):

BadImageFormatException: Could not resolve field token 0x04000259, due to: Could not load type of field 'HutongGames.PlayMakerEditor.FsmEditor:prefabTypeLastUpdate' (42) due to: Could not resolve type with token 0100009e (from typeref, class/assembly UnityEditor.PrefabAssetType, UnityEditor, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null) assembly:UnityEditor, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null type:UnityEditor.PrefabAssetType member:(null) signature:<none> assembly:C:\Users\Flarb\Documents\Unity\DEMON'S TILT (1) - REVERT\Assets\PlayMaker\Editor\PlayMakerEditor.dll type:FsmEditor member:(null) signature:<none>

Hi, it looks like Unity is still trying to use the version of PlayMaker for 2018.3. There is an Asset Store bug that uses the last version downloaded even if it's not for the version of Unity you're currently running. You have to manually update PlayMaker in the Asset Store while running 2018.2 to get the correct version (then import and install).

We're looking into a workaround for that Unity build bug in 2018.3. Should hopefully have a fix soon...

How do you manually update? I tried deleting the folder and re-installing to no avail. Do I have to blow away the downloaded cache somewhere?

Also what timeline is "soon" on 2018.3 support? I'd love to upgrade to 2018.3 ASAP.

Yeah, you need to update the Asset Store cache. I switch to the old Asset Store UI, go to downloads, find the asset and update/download. I remember the new Asset Store UI being buggy, but they might have fixed that...

I'm trying to get more details on the build bug from Unity. I'd love to get it fixed asap!

Hi,

 yes, this is really a pain also, a quicker way is to locate the assetStore cache folder on your hardrive and directly delete it here, the old Asset Store UI takes ages to get that process done, while if you have a shortcut to the folder directly, it's quicker.
