Article Number: 000034878 | Last Modified: 2019/01/17
Description
- QlikView task fails with error System.IO.FileNotFoundException: Could not load file or assembly 'DMSFileSystemHandler, both on manual or scheduled trigger.
- Qlikview Distribution Service (QDS) continuously reports error messages "Failed to calculate load; Function returned NaN" every 4-5 seconds in the Windows Event log.
Cause
Is has been noted in a number of cases before that the config file QVDistributionService.exe.config was somehow renamed to QVDistributionService.exe.config.txt.
Resolution
- Locate the file QVDistributionService.exe.config under C:\Program Files\QlikView\Distribution Service. In Windows File Explorer, check option View > File name extensions to make sure the file name is QVDistributionService.exe.config, not QVDistributionService.exe.config.txt
- If the file has been renamed to QVDistributionService.exe.config.txt, stop QDS service, rename the file name to remove the .txt extension and start the service again.
