This is a very annoying problem while generating release build files. Here is the steps I did while buiding:
1. Select Project > Export Release Build
2. Select Signed Native Installer
3. Import certificate
4. Click Next.
I always got the following error:
I have the following setup:
OS: Windows 8.1
System type: 64-bit
Flash Builder Version: 4.6 Premium
Installed FB: FlashBuilder_4_6_LS10.exe
Please help. This is giving me a lot of headaches for a couple of days now.
