I am running putty.bat file. Inside bat file I am writing del command to remove unnnecessary files which part of putty needs to be deleted

Question

After running the batfile, putty is getting installed but del command should remove the unnecessary files part of putty, it is not deleting. my installing directory: C:\Amaze\tool

start msiexec.exe /i %~dp0putty-64bit-0.74-installer.msi > putty_log.txt 2>&1

del "%TARGETDIR%\putty-64bit-0.74-installer.msi.sha1"

The del command should remove the files of putty but it is not happening.

del "%TARGETDIR%\putty-64bit-0.74-installer.msi.sha1". Is there any issue with the del command and 
%TARGETDIR% is it going to path C:\Amaze\tool. 

Installer should run after installer runs the files needs to be deleted. why I am unable to delete files, let me know what needs to be done so that I can remove the files.

I tried this step and it is working:

start /wait /i %~dp07z1900-x64.exe > puttylog.txt 2>&1

del %~dp0putty*
