Hi, I have installed the WDTC according to the online cource but I am getting following error, see picture. Does anyone know how to check the installation paths? [image]

It seems to be an issue with the path for some reason. We set it up according to the documentation. C:\WD\6.32\ But if shorten the path to C:\WD then it works. Can it be a issue with the build code? Sidenote; It works if you use the directory name with the version number. C:\WD631

Hi @johan.dehn in my case I had to modify the file in C:\WD\package.json with the correct mappView version. [image] Take care of node js version too, it must be 16.17.0, otherwise, you’re going to get an error. BR Vanessa

The versions seems to be correct in our case, however we are running the later 6.3.1. Hmm. [image]

Ok, probably there is a new WDTC version for AS 6.3. Because I had for AS 6.1.1 the mappView_WDTC_6.1.1.0.zip file.

Hello @johan.dehn , Maybe just a detail, but please make sure that you select “Add to PATH” when installing the node version 16.17 [image] The second thing which you can check: GitHub - nodejs/node: Node.js JavaScript runtime :sparkles::turtle::rocket::sparkles: Best regards, Patrik

Customer has the nodejs install path given in the system environment variables. He has tried to revert to 6.1.1 with same fault. Does your path look the same,? I guess it can differ due to were you like to put things. [image]

In my case, the cause was old AS files in the C:\BRAutomation folder. I removed them and ran the PowerShell installation steps again—now everything works. [image]

@jones When you say “old AS files” what more exactly do you mean ? What files did you remove?

Hello Johan I deleted the whole folder. there should no longer be any AS files in C:\Brautomation. I had to uninstall AS 4.12 to remove it because the German version was still installed in this path. I have no idea why there was still an AS and AS6_ES folder in there, but I was able to simply delet…
