My TF.exe is strangely gone 0KB and not operating

Question

I have been trying to automate some deployment and regularly used tf.exe through .bat files. I recently started getting "this app can't run on your pc" on my .bat files and upon checking I saw my tf.exe is 0KB.

following is the example of a ```.bat`` files I usually ran.

SET tfs=http://vm03:8080/tfs

SET chg= %1

"%programfiles(x86)%\Microsoft Visual Studio 14.0\Common7\IDE\TF.exe" 
 changeset /server:%tfs% %chg% /noprompt

I am using 64-bit windows 10. anyway I can have tf.exe reinstalled? and can anyone explain what happened?

edit: I have another instance of visual studio 17, and I am using its tf.exe however what happened to my original tf.exe is still unknown. Anything to help me understand will be great.
