Problems with compiling lftools.mlib for Stata17

[bpiccirillo]

Upon running ftools, compile , to compile lftools.mlib for Stata 17, I get an error message. The code stops because Stata is unable to find the unlink_folder.

I have already installed the following packages

• ftools (version 2.49.0)
• reghdfe (version 5.7.3)
• ivreg2 (from SSC)
• moremata (from SSC)
• ranktest (from SSC)

Do I need to install another package which lftools.mlib is part of?

Thank you!
