# Open applications

Open an application when you start FactoryTalk View Studio or when FactoryTalk View Studio is open.

FactoryTalk View Machine Edition application files are converted to the current version of FactoryTalk View when you open them. Once the application has been converted, it cannot be opened by earlier versions of FactoryTalk View Studio. However, you can still use the current version of FactoryTalk View Studio to create runtime application files that will run on earlier versions of ME Station.

If an application was created in earlier versions of FactoryTalk View Machine Edition, when you open the application in current version FactoryTalk View Studio, ensure that the application's IP addresses do not contain a leading zero. FactoryTalk Linx interprets a leading zero as an octal notation. For example, the IP address 131.200.13.111 is valid, but 131.200.013.111 is invalid. Before opening the application, edit the application's Nodes.csv file in Notepad by removing leading zeroes in IP addresses.

To open an application in FactoryTalk View Studio, the logged-in user must have read/write access to the sub-folder that holds the HMI applications. If the security designation for FactoryTalk View Studio users is Power Users, they may not have write access.

## To open an application

1. If FactoryTalk View Studio is not started, start FactoryTalk View Studio.

   The resolution and version that was last used to open the application is shown.
