After opening a company in POS (Process - Point of Sale) receive a Run-time error -2147467259 (80004005) : Not a valid bookmark. and then it closes.
This is on the Main PC which is running Windows 10., Pervasive 10
The same thing occurs on the workstation, which is running Windows 7, Pervasive 10 - but it also has Run-time error 91 and then closes.
It has been running fine for absolute ages, until this morning.
Checked windows updates, nothing recent in the last few days.
Have uninstalled, reinstalled, re-registered (even cleared the registry), uninstalled and reinstalled POS, uninstalled and reinstalled Pervasive (only on the main PC).
Any other suggestions (though I think the next step is formatting Windows)
