1.Problems
Sometimes there is update tip when customers download project from PC to HMI, the tip as FIG 1 shows.
But when customers select “OK”, software can’t finish the update for HMI, it will shows error tip as FIG 2 shows, and when customers click “OK” for trying again, it is never successful, but when customers click “Cancel”, then download will continue, new project could display in HMI.
2. Solution
This problem is caused by permissions issue, so there are two solutions for it.
2.1 Run as administrator
Please set LeviStudioU software runs as administrator in your PC, so that we could update firmware successfully.
2.2 Install software in other disk
Most customers accustomed to install software in system disk, so it leads the permissions issue, we suggest customers install software in other disk, like D, E and so on. And then we could update HMI firmware without administrator permissions.
