When trying to launch Agile Requirements Designer(ARD), the dialog shows the error message:
Qt5Core.dll not found. File must be available to run the application!
We are unable to continue to use the product.
ARD 2.10, 3.x
CA Agile Requirements Designer
This error message occurs when one/some of the redistributables for VC++ 2012, 2013 and 2015 is/are missing on the system.
The redistributable for VC++ 2012, 2013 and 2015 must be installed before installing the ARD from the information of the Installation Prerequisites.
If for whatever reason the redistributables for VC++ 2012, 2013 and 2015 do not get installed, then you will need to install them manually, then try to launch ARD again to see if the problem is resolved or not.
Here are the links needed to download the files:
If you can install the Service Pack 1 for Windows Server 2012/2008 then VC++ 2015 will work straight away.
If that fails, then it is because of a missing update KB2999226.
Following the instructions from
Download KB2999226 for your OS from : https://support.microsoft.com/en-us/kb/2999226
To install this update, you must have April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) installed in Windows 8.1 or Windows Server 2012 R2. Or, install Service Pack 1 for Windows 7 or Windows Server 2008 R2. Or, install Service Pack 2 for Windows Vista and for Windows Server 2008.
Windows Server 2012 R2 Update (KB2919355) : https://www.microsoft.com/en-us/download/details.aspx?id=42334
Prerequisites for KB2999226 which is included in the VC Redist packages.
KB2919442 is a prerequisite for Windows Server 2012 R2 Update and should be installed before attempting to install KB2919355
These KB's must be installed in the following order: clearcompressionflag.exe, KB2919355, KB2932046, KB2959977, KB2937592, KB2938439, and KB2934018.
Unfortunately VC++2015 is a prerequisite for ARD to run and the easiest option would be to update Windows to the latest security update and the error should disappear.
If you still have the problem even after installing the redistributables for VC++ 2012, 2013 and 2015, please copy the msvcp140.dll, vcruntime140.dll and vccorlib140.dll files from the folder "C:\Windows\System32" and paste them in the "C:\Program Files\Grid-Tools\AgileDesigner" folder or "C:\Program Files\CA\AgileDesigner" folder, depending on where ARD was installed. Then try to launch ARD.
