I’ve been trying for the last two days to install TMC on Visual Studio (which I installed in 2023 without any issues). Following the instructions given at “https://www.mooc.fi/en/installation/vscode/#installing-vscode”, I tried to install TMC, but I keep getting the same error:
“[2026-06-08 05:13:47:990] [INFO] TMC-Langs version: tmc-langs-cli-x86_64-pc-windows-msvc-0.39.4.exe

The CLI folder mentioned as not empty, is empty. I tried deleting the directory mentioned, uninstalling and reinstalling TMC, and also Visual Studio. I have disabled the antivirus software, I tried manually downloading the file ‘temp-tmc-langs-cli-x86_64-pc-windows-msvc-0.39.4.exe’ but it didn’t work. I also tried various versions of Java. I also tried with “VSCodeSetup-x64-1.123.0” and “VSCodeUserSetup-x64-1.123.0”. I’ve also tried it on two different computers but same problem.
Thanks for your help!
