由于安装程序文件已损坏，无法安装该应用程序。 尝试从应用程序作者那里获取新的安装程序文件

Question

We have an old version of our application that was successfully code signed using a Thawte SHA 256 certificate. This certificate expired and we are now using a new one.

When the user upgrades from the old version of the application to the latest, they encounter this error: Reinstalling the application gets around the issue but we want a more professional solution.

I used the following shell script to sign it, which seems to run successfully, but am still getting the error

if (($# < 1))
then
echo "Usage: $0 version"
exit -1
fi
echo "Fixing file permissions..."
chmod a+x bin-debug/bin/SWC

echo "packaging Air file for mac..."
cd bin-debug

/Volumes/Macintosh\ HD/Users/Shared/flex_sdk_4.6/bin/adt -package -storetype pkcs12  -keystore ../../../thawte\ certificates/airSigningBackup2018.p12 -storepass myPassword -target air ../SW_Desktop_mac.air DieBook-app.xml DieBook.swf bin/SWCM bin/SWCMLE builddate icons
cd ..

/Volumes/Macintosh\ HD/Users/Shared/flex_sdk_4.6/bin/adt -migrate -storetype pkcs12 -keystore ../../thawte\ certificates/airSigningBackup2016.p12 -storepass myPassword SW_Desktop_mac.air SW_Desktop_mac_migrated.air

/Volumes/Macintosh\ HD/Users/Shared/flex_sdk_4.6/bin/adt -package -target native SWD_$1.dmg SW_Desktop_mac_migrated.air

echo "SWD_$1.dmg should be ready now."

As far as i remember, this issue happens when you have multiple versions of the same app with same version number installed. I don't remember if its the verison number but i'm sure it's one of the unique identifiers ind the XML. So for each new version change that identifier and all should be well.
