IISExpress stopped working after installing IBM MQ client 9.1.4 along with 7.5

  • 1.  IISExpress stopped working after installing IBM MQ client 9.1.4 along with 7.5

    Posted Mon September 09, 2024 12:51 PM

    IBM MQ client 7.5 was already installed on the system which is primary. Then I installed IBM MQ client 9.1.4 and made it secondary.

    After that my ASP.Net applications that I run from Visual Studio using IISExpress has stopped working which connects to 7.5. Web applications hosted on IIS are working fine. Any console or desktop application is also working fine.

    Getting following error in Event Viewer when trying to connect to IBM MQ 7.5

    Faulting application name: iisexpress.exe, version: 10.0.26013.1000, time stamp: 0x64d3330b

    Whether I run IISExpress as 32 bit or 64 bit doesn't matter. The user who is running Visual Studio is administrator and has full rights on machine. Any idea how to make it work?
