I tried deploy a windows application using windeployqt. I used the qmldir switch along with it and it copying all the dependencies to the exe directory and it is working perfectly fine in my system but the application is not loading in another pc. It does not show any errors for it and it has redistributables(2015,2017) installed too and yet the application is not at all loading. Iam pretty sure that all the qt platform plugins and other dll's are also installed but still tough luck the application doesnt work in a different pc. Can someone help me as to what could be the issue. It is a very urgent project that needs to be completed before this weekend. Please help.

@Janani If you start the deployed application on another PC from a terminal - do you see any warnings/errors? Also, you can use https://www.dependencywalker.com/ to check what is missing.

@Janani Then use Dependency Walker on the machine where the app does not work.

@jsulm I tried the dependency walker to check where have I gone wrong but again it showed on api-win*.dll's missing, most of the forums tells me to ignore those dependencies. I downloaded the redistributables also but in vain. I dont know why is this happening. Sitting in this issue for more than a week now.

@Janani Did you also try to disable anti-virus software?

@jsulm I tried that also, no use. I have this doubt, using windeployqt did not actually install msvcp140.dll and vcruntime140.dll automatically. I added them manually and deployed it in a different pc and checked it still did not work. I have no clue on why is this happening. Its difficult to debug without any errors also.

@Janani I would also check the Windows event log - maybe you find some hints there?
