HTTP error code 12029 when trying to install compiled app

I built a DLL on R2015b/W7 64-bit. I can install it (MyAppInstaller_web.exe) on my W10 machine but not on the W7 computer it was built on? I keep getting the HTTP error code 12029 exception.

Any ideas? Have tried everything I found online to address the issue with no luck. Thanks.

You are probably running into a challenge that most places stopped supporting an older HTTPS encryption.

See https://www.mathworks.com/support/bugreports/1741173 for a potential java.opts work-around. Or see it summarized at https://www.mathworks.com/matlabcentral/answers/401291-using-tlsv1-2-with-webread#answer_321261

You might have to change the java.opts file before you build the application.

And since you are targetting the Windows 7 machine, you might have to do this in the reverse sense -- you might have to configure it for an earlier encryption standard instead of TLS1,2

Thank you, Walter. Adding the java.opts file didn't help (ML is definitely picking up on it) but I will play with it some more.
