问题
I'm getting the following error when trying to upgrade an application I wrote:
Sorry an error occurred
The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid. Please contact the application author.
Here is a screenshot:
I'm the application author. I recently created a new project and copied the old project files to the new location.
Is this due to that or am I possibly using a different certificate somehow? In the drop down list I have multiple entries pointing to same cert. I will try going through them but I'm wondering too if it's possible if anyone else has run into this issue.
回答1:
I was using the incorrect cert. When I created a new project, Flash Builder preloaded certs from somewhere. They looked correct, however, the cert I was using was not in that list. So I opened the previous project and found a cert from that the project was using. After recompiling and attempting to update, the install went correctly with no error.
