Hello,
Are you testing the package on a Windows XP SP2?
If yes, please keep in mind that packages created with an older version of Advanced Installer than 12.5 are not supported on Windows XP SP2.
More information about this can be found in our
"Advanced Installer Requirements" article.
With that being said, in order to create a package that is compatible with Windows XP Sp2, please download Advanced Installer 12.5.
If that is not the case, please give me some more details about the encountered issue.
Hope that helps.
Best regards,
Catalin
