[wix-users] Managed Bootstrapper Application Host - Upgrade from WiX 3.8 to 3.10 error

[khacminh ho]

Hi,
I started using WiX with version 3.8 and everything works fine, including create *.msi file and Bootstrapper *.exe installation file. I can also create installation UI for my own. Now my company upgrade VS 2013 to VS 2015 and WiX 3.8 is now incompatible. Therefore, I have to upgrade WiX 3.8 to 3.10.2. And now my custom UI installer cannot work any more. I check the log file and get the following error:
[1ACC:029C][2016-07-05T12:41:03]e000: Error 0x80070003: Failed to open handle to engine process path: C:\Users\MinhHo\AppData\Local\Temp\{5B7E6773-DC64-4BAD-8E5A-F2EA0EEAEC98}\.cr\MyInstaller.exe[1ACC:029C][2016-07-05T12:41:03]e000: Error 0x80070003: Failed to initialize engine section.[1ACC:029C][2016-07-05T12:41:03]e000: Error 0x80070003: Failed to initialize engine state.
