I am in a process of upgrading our MQ server form 6 to 7.1, I have completed this activity on 3 of MQ servers already, everything is fine and systeam is up and running OK. but when I tried to do this upgrade on one of our last server, it thrown error that
"Error 1714, the older version of IBM Websphere MQ cannot be removed. Contact your technical support group",
During upgrade, popped up that IBM Websphere MQ.msi file is unable to find in the path where it supposed to be, as per registry this file should be in local system, I tried two option to over come this problem
1) first I selected this file from network path where we keep MQ6 s/w's, but this wasn't helped.
2) and then I created a folder in local system and copied this .msi file as per registry entry, but this is also not helped.
any help is much appreciated.
