TIBCO Spotfire analysis (.dxp) fails to open with the error "The file is not a valid DXP file"

TIBCO Spotfire analysis (.dxp) fails to open with the error "The file is not a valid DXP file"

When you try to open a DXP file in the TIBCO Spotfire Analyst Client, it may fail to open and returns the error "The file is not a valid DXP file". For example:

Error message: Unable to read the file xyz.dxp. The file is not a valid DXP file.

This can be caused by an issue which allowed incomplete or corrupt dxp files to get saved to disk or to the TIBCO Spotfire library. There is a fix that is released in the TIBCO Spotfire Server and TIBCO Spotfire client hotfixes which introduces validation during saving to prevent this issue. The related fixed issues are:

• TSS-22405 - TIBCO Spotfire now validates transferred content while opening items in the Spotfire library as well as transferred data when using Information Services if both client and server supports that.
• TS-54780, TS-54773 - TIBCO Spotfire now validates transferred content while opening or saving items in the Spotfire library as well as transferred data when using Information Services if both client and server supports that.

To avoid this issue moving forward, apply the hotfixes relevant to your Spotfire version on both the TIBCO Spotfire Server and the TIBCO Spotfire Analyst client:

• TIBCO Spotfire Server:
  • TSS_7.12.0 HF-001 or higher
  • TSS_7.11.0 LTS HF-004 or higher
  • TSS_7.10.0 HF-004 or higher
  • TSS_7.9.0 HF-004 or higher
  • TSS_7.8.1 HF-010 or higher
• TIBCO Spotfire Analyst client
  • TS_7.12.0.59 HF-001 or higher
  • TS_7.11.0.79 LTS HF-004 or higher
  • TS_7.10.1.13 HF-007 or higher
  • TS_7.9.1.17 HF-008 or higher
  • TS_7.8.0.39 HF-012 or higher

Please note that these fixes will NOT fix already corrupted dxp files, but will instead only help prevent the corruption from occurring in the future. Any corrupt dxp files will need to be manually restored from a backup or earlier version of the dxp file. Wiki: List of hotfixes for TIBCO Spotfire Server
