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 the Microsoft Dynamics AX Client executable: C:\Program Files (x86)\Microsoft Dynamics AX\50\Client\bin\ax32.exe “-regconfig=Ax2009myConfig” “-logdir=C:\Documents and Settings\All Users\Application Data\Microsoft\Dynamics AX\Dynamics AX Setup Logs\2009-10-21 12-37-06” “-startupcmd=autorun_C:\Documents and Settings\All Users\Application Data\Microsoft\Dynamics AX\Dynamics AX Setup Logs\2009-10-21 12-37-06\GetVersionInformation.xml”
Message: Version string portion was too short or too long.
FullText: System.ArgumentException: Version string portion was too short or too long.
at System.Version..ctor(String version)
at Microsoft.Dynamics.Setup.InstallApplicationHotfix.ProcessVersionInformation(String logFilename, String versionFilename)
==== Setup encountered an unhandled exception and could not be completed. For details see the previous messages in the log. ===
What was the problem?
The important information was:
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:
We then found out that this method has been changed so it returns also the build number of our customizations.
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.
