Applies to: All products, when used with Excel 2016, Excel 2013, or 64-bit Excel 2010
At some point during execution of @RISK (Evolver, NeuralTools, PrecisionTree, StatTools, or TopRank), I get the message
PalOutOfProcessServer7 has stopped working
or
PalOutOfProcessServer6 has stopped working
This is not a licensing issue, even if you see "Authorizing" in the Excel status line. PalOutOfProcessServer is the bridge from @RISK and our other software to 64-bit Excel 2010, or to Excel 2013 and newer Excels. If PalOutOfProcessServer can't load, then the rest of @RISK can't talk to Excel.
This error could result from a number of different conditions. What follows is a list of the known causes. Please try each of these first, but if none of them resolved the problem please contact Palisade Technical Support.
One possibility is a lack of proper permissions during install. In Windows Vista and later, please reinstall by right-clicking the installer and selecting Run as administrator. In Windows XP, log on with full administrative rights and run the installer by double-clicking. Either way, if you get a screen asking about repair, modify, or remove, select Repair. If you get a Customer Information screen, change 15-day trial to I am upgrading or reinstalling.
Perhaps our software didn't shut down cleanly the last time. You could open Task Manager and close any open processes related to our software, but it's easier and more effective just to restart Windows.
We occasionally see security software blocking one or another of our processes, so try disabling your anti-virus or anti-malware software temporarily and see if that lets everything run normally. If it does, please report the false positive to your anti-malware or anti-virus software vendor.
You may have a DEP setting that prevents our software from running. See Data Execution Prevention to test this, and for advice on fixing the problem.
