sandiworld Posted September 7, 2009 Report Share Posted September 7, 2009 Hi,When I try to install any MSI using "MsiInstallProduct" and if another installation is going on, it fails with an error Error 1618: Another installation is already in progress. Complete that installation before proceeding with this install.I want to handle this situation like, my MSI should not fail in this case instead should wait until the another installation finishes.Is there anything like a flag or lock we can use with the API "MsiInstallProduct".Any ideas regarding this would be highly appreciated.

Boris Posted September 7, 2009 Report Share Posted September 7, 2009 This issue occurs because Microsoft Windows Installer can only run one installation at a time unless it is a nested installation.See :- http://support.microsoft.com/kb/822454For more information about nested installations, visit the following Microsoft Web site:http://msdn2.microsoft.com/en-us/library/aa368010.aspx Quote Link to comment Share on other sites More sharing options...
