Hello,
After building a setup file
and while trying to install an application by running this setup file
something wrong is happening while executing a custom action.
To find out what's going wrong, I need to debug the code which is C/C++
code in Microsoft Visual Studio 2017.
To do that, I've put a "MessageBox()" function call in the custom action
code:
MessageBox(NULL, L"*** (Custom action) Please attach a debugger. ***",
L"(Custom action) Debug", MB_OK);
When I start the installation, the message box pops up.
In Visual Studio 2017, I select the menu "Debug -> Attach to process...".
I select the entry in the "Available processes" list :
------------+-----+--------------------------+------+-----------------------+-----------
Process | ... | Title | Type | User
name | Session
------------+-----+--------------------------+------+-----------------------+-----------
msiexec.exe | ... | (Custom action) Debug | x86 |
<hostname>\<username> | 9
------------+-----+--------------------------+------+-----------------------+-----------
and click "Attach".
<hostname> is my machine name.
<username> is my system user name.
I get the error message:
"Unable to attach to process. Access is denied."
I have tried to make it work with no success.
Can you advise me what to do to be able to debug my custom action code?
Thank you.
Best regards.
