If a program is run on RAM and Encrypted boxes when the sandbox root folder is not present, the programs will not run

[offhub]

Describe what you noticed and did

If a program is run on RAM and Encrypted boxes when the sandbox root is not present, the programs will not run.

• Ram Box:

1. Create a Ram Box
2. Rename BoxRootFolder or set FileRootPath to different folder (e.g. C:\Sandbox to C:\Sandbox_)
3. Run a program in the sandbox

SBIE2230 Failed to mount root for New_Box [xx / yy]
SBIE2335 Initialization failed for process Start.exe [xx / yy]

Result: Sandboxie creates an empty file with the box name instead of the junction folder. (e.g. C:\Sandbox\user\New_Box)

• Encrypted Box:

1. Create an Encrypted Box
2. Rename BoxRootFolder or set FileRootPath to different folder (e.g. C:\Sandbox to C:\Sandbox_)
3. Run a program in the sandbox

SBIE2241 Box image file C:\Sandbox\user\New_Box.box could not be opened   

Result: Sandboxie does not create any folders.

I ant reproduce this one, also the Encrypted Box deletes the folder when it unmounts to not sure how you renamed it? mounting manually renaming and then trying to run something?

[offhub]

Let's assume that the C:\Sandbox folder is set as the root, and that this folder has not yet been created. In this situation, when we try to run the Ram/Encrypted boxes that we have previously configured, we get the above errors.

aaa i see you mean the folder which contains the sandbox root folder,ok wil check this out asap

[DavidXanatos]

Rambox fixed,
encrypted box, well that works as expected, when you move the box image out of the way if can not mount it, and we don't have a way to find it.

Encrypted Box:

1. If there is no matching .box file when we want to mount the box image, a password window opens to create a new .box file.
   • After this stage, a new .box file cannot be created because the root folder does not exist.
   • If the root folder does not exist, it should be created first.
2. However, the window to mount the box image opens as if the .box file had been created successfully, and when the password is entered it gives the error: SBIE2241 Box image file C:\Sandbox\user\New_Box.box could not be opened
