Hey there @papa_chonk, thanks for taking the time to get in touch. I am sorry to hear that you have been experiencing issues installing Trackmania. Could you please go through this technical troubleshooting article for me ensuring you have completed all of the steps? These steps can help rule out many of the common causes for technical-related issues. I understand you have already performed several actions to try and remedy the issue such as verifying your files through connect, but we must cover everything in the article first.
I have checked into it from my side, and we are not aware of any issues that would be causing this. I will keep an eye out and let you know about any new developments.
Also in the future, can you please consider creating your own thread if there is not something active already regarding what you have mentioned? This unnecessarily raises forum traffic and moves more active threads down the page.
Should you have further questions regarding any of those steps in the article above, or regarding any other issue, please do not hesitate to let me know.
