[BlindRUG] BrailleR error message

[Péter Zsigmond]

Hello!

I want to install the BrailleR package, but I get error messages. 
Windows 10, 64 bites. I  started R x64 4.0.4 as admin. I have entered 
these commands:

if(!require(remotes)) {install.packages("remotes")}

remotes::install_github('ajrgodfrey/BrailleR')

But I get this error message.

The downloaded binary packages are in
         C:\Users\Péter 
Zsigmond\AppData\Local\Temp\Rtmpq2JUX9\downloaded_packages
Error: Failed to install 'BrailleR' from GitHub:
   create process 'C:/PROGRA~1/R/R-40~1.4/bin/x64/Rcmd.exe' (system 
error 267, invalid directory name) @win/processx.c:1040 (processx_exec)
 >


What can I do? Can You helpme?
Happy day to you!

Peter
