@DeepakBisht-1625 What OS did you use for the server? Did you meet this issue when doing the same on another server?
There is a post that discussed this similar issue, the following is quoted from Alexandr's reply in the post, you can check the post for the detailed information:
"
Solved the problem as follows:
1. I took files from the cache from another farm.
2. Put them in %LocalAppData%\Microsoft\Web Platform Installer\installers
3. Launched Web PI
4. A miracle happened! Installation started.
"

If this issue still exists, I suggest you create a new thread on the Web Platform Installer community, more professionals will assist you with this issue.

I ran into exactly same problem and was able to solve it.

Copy the Workfow_Manager.msi from temporary files of WPI and paste it somewhere you can navigate easily through PowerShell and run below command.

.\Workflow_Manager.msi IACCEPTEULA=yes WEBPI=1

Later, you must install the CU 5 for WFM.

Check the complete guide on the solution here.
