On some systems, you may get an error message when trying to install XSMP or another application. Or the installer may not start at all.

Error: Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item

Here is some troubleshooting that you can do to fix this problem.

Solution 1: Unblock the installer
1. Right-click on the Installer and select properties
2. Check the option "Unblock"
3. Click on Apply and Ok to save the change
4. Then try to install it again

Solution 2: Run the compatibility troubleshooter
1. Right-click on the Installer and select properties
2. Click on the Compatibility tab
3. Then click on "Run compatibility troubleshooter" and follow the instructions

Solution 3: Enable the Installer logs
1. Click on Start, search for the Command Prompt
2. Right-click on that then click on "Run as Administrator"
3. Run this command:
"C:\Users\Your_user\path_to_installer\setup.exe" /v"/l*v C:\Users\Your_user\path_to_installer\LogFile.log"
4. Where "C:\Users\Your_user\path_to_installer\setup.exe" is the path to the EXE installation file, and "C:\Users\Your_user\path_to_installer\LogFile.log" is the path to the file to be used to output the log file.
5. Then open the LogFile.log to check what is causing the problem.
