Check if the error produces a log file in C:\Program Files (x86)\Common Files\Microsoft Shared\VFP

Sometimes that produces some information that can at least show you which method raised the error.

>Hi All,

>Just in one week time we have two customers who have upgraded their workstations to Windows 10 calling for support because of our application errors out with a C5. The point of where it happens seems to be random.
>
>So far I have advised them to
>- Check the network driver
>- Check the printer driver and test while a different printer is the default printer
>- Check the graphics driver and upgrade that if needed
>- Disable the virus scanner temporarily to see whether it makes a difference
>
>- Delete the user profile on that machine and restart Windows
>
>Though I'm not able to check whether they all try that, it sounds like the problems are still there.
>
>This application has been very stable so far, and this particular build has been running on hundreds of workstations without a problemin the past, so I pretty much rule out it is our application.
>We are running our application with SET RESOURCE OFF, so it also does not have anything to do with foxusers.dbf
>
>
>Does anyone have the same experience with Windows 10 and a VFP9 app ?
