Sandboxie 3.70 and ProxyCap 5.03 do not work at all together.

I do have ProxyCap selected in the software compatibility section, but it just won't proxify sandboxed applications.

Is there a way to deal with this issue?

It's working here. Sandboxie 3.72 x64, Windows 7 x64, ProxyCap 5.03 x64.

What is NOT working: E.G. Installing a program directly and only in Sandboxie.
But having a program normally installed and putting it THEN in a new Sandbox is working.

Hi, Jennifer. Applications installed inside sandboxes do not get proxified by ProxyCap.

Windows 7 x64, ProxyCap 5.03 x64, Sandboxie 3.70 x64 here as well.

I'm running an older ProxyCap version (4.x) just in case Sandboxie is optimized for it, but I still don't get any positive results. Is there really no way to make an application which is instsalled in a sandbox to work with ProxyCap? I need to use ProxyCap because it is able to transport TCP as well as UDP.

UPDATE: Okay, as Jennifer said, applications get proxified correctly by ProxyCap if they are not initially installed in a sandbox.
It would've been nice if applications installed in sandboxes could've been proxified as well.
Is there any chance to have that working in the future?

Perhaps. I'll have to look into it. Will take me some time to get to this, I'm afraid.

How can I try to reproduce the problem? Do I just install ProxyCap and then install some browser in the sandbox, and then the browser should not be able to connect anywhere? Or are there any settings that I need to configure somewhere?

Hello.

First, you need to install ProxyCap on the main system, then you have to specify a working proxy server and the applications which should get proxified (it doesn't use full paths, just executable names).

Then for the test, you should install a browser and IP checker inside a sandbox, and of course, have their executables set as proxified applications in ProxyCap.

If proxification is successful, the browser should show the remote proxy server's IP when visiting a "what is my ip" site and the ip checker should show the remote proxy server's IP as well.

In case you do not have a second internet connection available and also a second computer to install a proxy server on (like CCProxy, with SOCKS5 authentication and TCP/UDP support), it will be very frustrating trying to find one on the internet. So, if that is a problem, I can provide authentication details for an unrestricted proxy server I own via PM, or chat client.

Thanks for the clarification. I don't think I would have access to any proxy servers, but I assumed that I could just configure a random IP address (like 1.1.1.1) into ProxyCap as the server. Then when I get connection failures in the sandbox it means the connections go through ProxyCap. If the connection works it would mean ProxyCap was bypassed. Do you think it would work this way?

You are right. It should be the way you described, so no actual proxy server is needed.
