We have a customer that are having problems after switching QlikView servers.
They have one app that they open with QlikView Desktop (not open from server) from a share.
After editing and trying to save it they get "file not found".
All users that have the same app but in different folders get the problem.
Any other apps in the same directory does not have the problem.
If they take a local copy to my documents the same problem will occur so feels like there is something in the app, in document settings the save options etc is checked.
Where you change in Windows Defender does not work, they already had this changed.
Found the problem, the name of the file was cashed and locked. Reboot fixed it.
