When installing the TIBCO Spotfire Analyst client, it may fail with the following error:

Error message: The installation failed due to an unknown problem.
See details for more information.

IOException at mscorlib:
Access to the path 'C:\Program Files (x86)\TIBCO\Spotfire\7.6.0\Modules\80f5d8c7-1d4e-4ef8-b56e-9f99bdadf528' is denied. (HRESULT: 80070005)

Most commonly this is caused by various anti-virus or security programs running on the computer which are preventing access to the folder/files required by the TIBCO Spotfire Analyst client during installation.  One example is Cylance, which attempts to prevent viruses from being installed as opposed to removing them once they are present.  Another possibility is Kaspersky, which protects computers from malware and suspicious program behavior.  Try temporarily disabling these programs to see if the program can be installed successfully.

Additionally, ensure the user running the installer has sufficient permissions to the install folders.

A ProcessMonitor log can also be generated during the installation process to look for other possible conflicts. See Process Monitor for more details.

If the issue persists after verifying the security programs and folder permissions, please contact TIBCO Spotfire Support at https://support.tibco.com/ for further assistance.
