Tracing Errors When Running the SAP Assistant 
Activating a Log File
Use
If you encounter errors when running the SAP Assistant, you can activate the Trace option, which then produces a log file if errors occur.
Since the SAP Assistant is using several SAP Automation components, it is helpful to the SAP Assistant development team to see the resulting log file for tracing the error to the component producing the error.
Procedure
Result
If errors occur, report them through SAPNet, and attach the log file produced by the trace tool.
Checking Version and Location of Underlying Components and DLLs
Use
In addition to activating the log file, you can verify that the major underlying components and DLLs for the SAP Assistant exist, and that they are of the correct version.
Procedure
The list includes the DLL or component name, followed by a colon, followed the full path to the component or DLL file, then followed by a version number.
If the line for the component (or the DLL) does not include those details, you may be missing the component. Try re-installing the SAP Assistant.
