Details

On occasion after upgrading stand-alone InTouch to a higher version on Windows 10, attempts to open Windows Viewer can fail with a popup window which states, “Your system may be running low on memory. Continue?”

The popup will disappear when OK is clicked but returned a few seconds later. This cycle continued for several minutes and then stop.

If you are running HistData, try starting WindowViewer without opening HistData and see if the issue resolves. If so, the following steps may prevent the warning with HistData running.

The solution is to use Notepad to edit the histdata.exe.manifest file located in C:\Program files(x86)\Wonderware\InTouch

Replace the line: <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>

with: <requestedExecutionLevel level="asInvoker" uiAccess="false"/>

Window Viewer should now open without the popup warning.
