SmartSights XLReporter does support connecting to InTouch historical data sources.  This consists of data logged to .LGH files from the InTouch Runtime.  The HistData utility is used to retrieve the data from the .LGH files.  

The following error may be seen in the XLReporter log if there is a problem in retrieving the historical data.

Start by verifying the .LGH files exist in the folder specified in XLReporter Project Explorer.

Next, check to be sure the HistData utility is running.  This should be added to the Windows startup to start before InTouch.  The HistData.exe file is located in the C:\Program Files (x86)\Wonderware\InTouch folder.  Check the Task Manager to ensure it is running.

Newer operating systems such as Window 10, 11 and Server 2016, 2019, 2022 and higher do require elevated permissions to access the InTouch data.  Grant the XLReport Project and Scheduler the ability to run as an administrator.  The executables are located in the following folder.

C:\XLReporter\bin

Right-click on both the XLRiProject.exe and XLRiSchedule.exe to select properties.  Check the checkbox for ‘Run this program as an administrator’ from the Compatibility tab.  Click on the OK button to save the change.

Restart histdata.exe and hdacc.exe when this change is made.  hdacc.exe should start automatically when histdata.exe is started.
