SYMPTOMS
When you install Microsoft Message Queue Server (MSMQ) on a disk drive whose free space is slightly over a multiple of 4 gigabytes (GB), the installation may fail with an error that indicates insufficient space to install MSMQ.



CAUSE
The calculation to determine free space truncates the high-order byte, resulting in a value that only shows the difference from the next-lower 4GB multiple. For example, a total free space of 12,200,000,000 bytes would only show as 200,000,000. If this value is less than the space required for the MSMQ installation (including the SQL Server requirements for MSMQ Site Controllers), the installation fails.
