The dialog ErrorDlg has the error style bit set, but is not

[AlexSkylink]

I have a msi file that I created using Visual Studio setup project. I imported the msi into Advanced Installer. I've added a Upgrade property to remove a msi that is already installed on the system and install the new msi.
When I test this new installer, I'm able to remove the existing msi and when it tries to install the new product I get the following error message and then it rolls back:
"The dialog ErrorDlg has the error style bit set, but is not an error dialog."

The interesting thing is that if the old msi doesn't exist (Which means I don't need to un-install existing msi) on the system and I just run the new msi, it works OK.

I'm not sure what to check in order to fix this issue. Any help is appreciated.

Hi,

This could happen if you have a .NET custom action in your project. In the following thread you can see a similar discussion.

If the solution is not in the above mentioned forum post please create a verbose log and send it along with the .aip file to support at advancedinstaller dot com so we can investigate it.

Regards,
Bogdan
