Why convert PART to EXE?
A .part file (used by Firefox, wget, aria2, and other download managers) is an incomplete copy of the file being downloaded - in this case a Windows executable. The missing bytes were never received. No converter can reconstruct data that does not exist, and a truncated .exe (Portable Executable format) fails its digital signature check and cannot be run safely.

Frequently asked questions
Can I rename `.part` to `.exe` and run it?
The download says it finished but the file still has `.part` in the name.
Is a `.part` file dangerous?
.part extension prevents the OS from treating the file as executable while the download runs; the underlying risk depends on where the download came from, the same as any executable.
