Hi @MitDenukN,

• Have you checked whether you can invoke a report directly from the Crystal Web Service without an issue? Please read the “How to check if the Crystal Web Service is running correctly?” section of the following documentation: https://docs.ifs.com/techdocs/foundation1/020_installation/400_installation_options/005_operational_reporting/110_configure_crystal_web_service/010_setup_cws/default.htm#Installing_and_configuring_Crystal_Web_Service
   
• Have you specified the System Parameters related to CWS correctly in IEE? Doc:
  https://docs.ifs.com/techdocs/foundation1/020_installation/400_installation_options/005_operational_reporting/110_configure_crystal_web_service/010_setup_cws/default.htm#Configuring_the_System_Parameters
   
• Do you get this issue for both Quick Reports and Operation Reports? 

Supporting OS versions for CWS in IFSAPP9 are as follows, so I’m not sure if your OS version could be causing issues:

Supported Crystal Runtime:

Regarding IIS, documentation says to use IIS 6, even for IFSAPP10:

Hope this helps!
