Error during Hotfix installation – “Version string portion was too short or too long”
Recently we had a problem when installing a Hotfix for AX 2009.
The installation stopped with an error and we could find the following information in the setup log:
=== Starting execution phase ===

What was the problem?
The important information was:
FullText: System.ArgumentException: Version string portion was too short or too long.
The AX Hotfix Installer is checking the AX version during the installation to ensure only valid fixes will be installed.
For this it is calling the following method within AX:
ApplicationVersion/BuildNo()
We then found out that this method has been changed so it returns also the build number of our customizations.
static SysBuildNo buildNo()
{
return ApplicationVersion::applBuildNo() + MyCustomization.myBuildNo();
}
{
return ApplicationVersion::applBuildNo() + MyCustomization.myBuildNo();
}
The result of this change was that the method returned a string that was not expected by the AX Hotfix Installer and the Installer stopped with an error message.
We could finally solve the problem by removing the additional code.
static SysBuildNo buildNo()
{
return ApplicationVersion::applBuildNo();
}
{
return ApplicationVersion::applBuildNo();
}
