TOPIC: Using project for iOS and Android

We want to make an app that can be used in iOS and Android. What's the best way to this? iOS has a different project format (.tsp2db) than Android (.tsp2). I can't find an import/export/save as function in the Windows version of the TeslaScada2 IDE.
We also have problems to start the Mac Os version of the TeslaScada2 IDE. We are using Mac OS X version 10.12.3. It seems like Java problem. See attachment

Hello,
To make Import file for iOS device click Menu->Import for iOS menu item (check that you use the last version of TeslaSCADA IDE 2.10). For more information you can download file "iOS User Manual" from here: teslascada.com/index.php/en/downloads/download-teslascada2.
About problem with MacOS version. We also have the last version of Mac OS X 10.12.3. And don't have the problem you described. According your attachment you use Virtual Box for your testing. Unfortunately we didn't test on Virtual machines and can't give you any recommendations.

Best regards,
Ruslan.

But is it possible to load a iOS device from a Windows PC?

Yes. It's possible to load project from Windows on iOS device.

And do you have to create an iOS project (.tsp2db) on MacOSX or is it possible to use the WIndows (.tsp2) project?

iOS project (.tsp2db) based on SQLLite database. It's possible to use Windows version of TeslaSCADA2 IDE to create this type of file. It's not necessary to use MacOSX for this purpose.
Care must be taken in order that imported file will have .tsp2db extension. Otherwise iOS version of TeslaSCADA2 Runtime will not find this file.
