When running the utility setup.exe for windows with the 21.0.3 image, Automic.Automation_21.0.3_2022-05-23.zip, or from the utility zip, Automation.Engine_Utility_Windows_21_0_3+build.1652700829579.zip, the following popup occurs:
Cannot find the source file '[DIR to image]\utility\windows\x64\\@ucyblgmx.exe' to install.
Release : 21.0.2
Component : AUTOMATION ENGINE
This has been fixed with the release of 21.0.3 HF1 available for download at downloads.automic.com
Workarounds - there are two possible workaround:
1) Copy files directly from the x64 directory into the utility\bin directory
2) Copy ucyblgmx.exe from 21.0.2 and put this into the x64 directory, then run setup.exe (also attached to this knowledge base article)
