"Runtime error 70: Permission Denied" error usually indicates that DesignBuilder is trying to access a file, folder, or resource that it does not have permission to use.

Here are several steps you can take to address this error:

1. Run the Application as an Administrator

Running the application with elevated privileges can resolve permission issues:

Right-click the application executable or shortcut.
Select "Run as administrator."

2. Windows UAC Settings

User Account Control (UAC) settings can sometimes interfere. Adjust the UAC settings, but be aware that lowering UAC can expose your system to security risks:

Type "UAC" in the Windows search bar and select "Change User Account Control settings."
Adjust the slider to a lower setting.

3. Check File/Folder Permissions

Ensure that the application has the necessary permissions to access the file or folder it needs. You can do this by:

Right-clicking the file or folder.
Selecting "Properties."
Navigating to the "Security" tab.
Ensuring that the appropriate user accounts have "Read" and "Write" permissions.
The folders that DesignBuilder uses are located at:
- C:\ProgramData\DesignBuilder
- C:\Users\username\AppData\Local

4. Antivirus and Security Software

Sometimes, antivirus or other security software can block access. Ensure that your application is whitelisted or trusted in these programs.

5. Check for Disk Issues

Run disk checking tools to ensure there are no issues with the file system:

Open Command Prompt as an administrator.
Run chkdsk /f.
