Hi,

Could I please grab your FMOD version number? Would it be possible to check if the location you’re trying to save or build the project to/from has write permissions and if the location isn’t subject to source control or synchronized to a cloud-based file upload service such as Dropbox? Also, you could check this link similar to your issue ([Bank Building - Parameter Error](https://qa.fmod.com/t/bank-building-parameter-error/17356)) to see if it helps. Please let me know if the issue persists.
