### File System Permission Requirements
RPA Builder needs full write access to folders that are critical to its functioning. To avoid issues during the setup process and subsequent RPA Builder executions, ensure that:
  * You install RPA Builder as an administrator
If you don’t run the setup file as an administrator, the installation process might not finish successfully. If this happens, make sure you reinstall RPA Builder by running the setup file as an administrator.
  * RPA Builder has full write access to these folders and any subfolders and files inside them:
    * `C:\Users\<USERNAME>\Documents\Mulesoft`
    * `C:\Users\Public\Documents\Mulesoft`
    * `C:\Users\<USERNAME>\AppData\Local\MuleSoft_LLC`
    * `C:\Users\<USERNAME>\AppData\Roaming\MuleSoft`
    * `C:\ProgramData\Mulesoft\RPABuilder\Cache`
  * Your environment isn’t blocking the execution of any RPA process
The operating system can block the execution of certain files. Make sure that all executable (`.exe`) files inside the RPA Builder home directory and its subfolders are allowed to run.


### Check for Software Interference
Some software can prevent RPA Builder from working properly. Resolve any software issues you find before installing RPA Builder.
Software | Problem | Solution  
---|---|---  
**Microsoft OneDrive** Microsoft OneDrive is an application for backing up data from a computer. |  When you turn on Microsoft OneDrive backup for the Documents folder on your computer, it moves this folder to a different location. When RPA Builder starts, it tries to clean up the cache folder, but OneDrive redirects this to the new location where RPA Builder doesn’t have permission to write:
  * From: `C:\Users\<username>\Documents\Mulesoft\Cache`
  * To: `C:\Users\<username>\OneDrive\Documents\Mulesoft\Cache`

This causes an error that you can find in the log files: `System.IO.IOException: Access to the path 'C:\Users\<username>\OneDrive\Documents\Mulesoft\Cache' is denied`. A user describes this problem in detail in a Microsoft Community thread. |  If you use RPA Builder on a computer that has OneDrive, don’t let OneDrive back up your Documents folder. The Microsoft OneDrive documentation explains how to exempt the Documents folder from the OneDrive backup.
