Read only project in a standalone MPS IDE

Hey forum!

I have a question regarding the fact that one can build a standalone MPS to distribute it to MPS. I used the wizard way and only customized the distribution file to only build a zip for Windows.

Furthermore the build went well and I tried to open the generated IDE on my coworkers PC. It opened successfully, but unfortunately the project was read only. Does someone have an idea what I did wrong here?
Any help is highly appreciated.
