How do I open DSE if there is an error of not having appropriate permissions?

The error message may look like:

Option 1: Windows Controlled Folder access may be blocking DesignSpark Electrical executable's access its dependencies inside the installation folder, which is generally in the Program Files directory. Allow the DSE executable (usual path: C:\Program Files\DesignSpark Electrical\bin_x64\DesignSparkElectrical.exe) controlled folder access by following these steps: https://www.thewindowsclub.com/how-to-allow-apps-through-controlled-folder-access 

Option 2: If you can get your Windows user account elevated to administrator permissions, then open the DSE program shortcut properties (right-click on the program icon to see it) and then enable the check mark in 'Run this program as an administrator' under 'Compatibility' settings.

Click OK to save this change. Now try running DSE.

Option 3: Ask your PC administrator to re-install the software but choose the destination folder to be the Documents folder under your standard Windows user account.
The default Program Files directory where DSE installs occur is usually locked for read/write by admins only.

Replace 'your_Windows_account' with your real Windows account name to find the correct folder path.

If neither option 1 or 2 have worked, try the below:

1. Try Method 1 (open properties -> security for DSE launcher C:\Program Files\DesignSpark Electrical\bin_x64\DesignSparkElectrical.exe and its folder C:\Program Files\DesignSpark Electrical) and check that all permissions are set to 'Allow' for the Windows account you are currently logged in with: https://support.microsoft.com/en-us/topic/-windows-cannot-access-the-specified-device-path-or-file-error-when-you-try-to-install-update-or-start-a-program-or-file-46361133-47ed-6967-c13e-e75d3cc29657
2. If 1 does not work, try the steps shown here: https://www.youtube.com/watch?v=tGLKjq_p0Rs It is a setting you need to toggle through Windows security centre about 'blocking new apps'. 
3. If you have different antivirus software, try to check if DesignSpark Electrical is in its list of locally blocked programs. If so, then remove it and try opening DSE again.
