I have recently installed python-2.7.14 (32-bit) on windows 10. But when I try to install any package using command pip install XXX, it gives me above error.

I tried all solution to this existing problem but it didn't work for me. My python is installed on C:\Python27

  • As my path didn't have any spaces there was no need to remove quotes from the path in pip.exe mentioned in the above commented duplicate link. python -m pip install XXX works for me but don't know why just pip install XXX is not working. But when I try to open jupyter notebook from cmd it gives me same error Fatal error in the launcher: Unable to create process using '"'. Hence I thought it might be some problem in my pip – Sachin Patel Feb 01 '18 at 03:16

python -m pip install XXX

worked for me but when I tried to open jupyter notebook in windows command prompt by typing

jupyter notebook

It used to give me the same Fatal error.

Actually, it was my antivirus mcafee at organisational level which was blocking the exe to run.

To solve this I had installed python in D:\ folder.
