Hello all,

I want to install my program on another computer. My aim is saving an image to a file for using later. But the image isn't being saved.

C#

image.Save(Application.StartupPath + "\\" + "data" + "\\" + "config" + "\\" + "Choosen.bmp");

(Application.StartupPath = C:\Program Files (x86)\PT\My Product Name)

There has to be an image in the directory after that line. It works when i execute the code from the solution, but it doesn't work when i set the program up on another computer. I prepared te setup project with InstallShield. I checked the directory (C:\Program Files (x86)\PT\My Product Name\data\config) , and it exists. I added all dll files which i used in solution project to setup project. Waiting for your helps.

Thanks

No, the image won't save.
When you install an application in production, it is installed in a folder below the "Program Files" or "Program Files (x86)" folded - and by default these folders are all write protected to help reduce the impact of Trojans, viruses, and so forth.

So when you try to write to it, you get an access violation and the file isn't written there.

While it is possible to get round this, it really isn't recommended - and there is no guarantee that it won't get even more restrictive in future releases of the OS) so the best thing to do is to change where you store data: Where should I store my data?[^] should help.
