This is caused by limited permissions for access to the file path specified in the error message, which is needed for performing the installation or upgrade. To avoid the issue, please check:
1) "Run as Administrator"
If this is a fresh installation, then right-click on the Installer and select "Run As Administrator".
If this is an upgrade, then open the TIBCO Spotfire installed client by right-clicking and selecting "Run As Administrator".
2) File/Folder Permissions
Ensure the user running the installation/upgrade has permissions to modify the files and folders referenced and used by the TIBCO Spotfire installed client
3) Security Applications
Ensure there are no security applications running on the local machine which may be blocking access to the path specified in the error message. For example, this may be an anti-virus, firewall, or end-point security application, among others. Check with your internal IT team to ensure the user has access to the required path.
After validating the above points, if you still have issues with installation, please open a support case with TIBCO Support at
