Hi,
probably your download is corrupt.
Try donwloading again. Maybe turn your “VirusScan on download” off.
This download will only work for IS Servers until 4.6.
For newer versions of IS (4.6 and newer) you will need WmWebSphereMQ_en_US.exe with additional ServicePack SP3 and a whole bunch of Fixes (Fix6 to Fix15).
If this a new application being developed on IS 6.x you should consider using webMethods MQAdapter 6.0 (& SP1) instead (It should be available via the webMethodsInstaller). SP1 requires IS_6-1_Fix40 to work correctly.
Regards,
Holger
