updateR keeps failing using both R console and Rstudio

Question

I have been trying to update the R version to the latest one. I used updateR provided by R package installr. I tried to run it from both R console and Rstudio. However, I got the same message as follows. Restarting R shows that the R version is still the old one.

> updateR()
Installing the newest version of R,
please wait for the installer file to be download and executed.
Be sure to click 'next' as needed...

The file was downloaded succesfully into:
C:\Users\abcd\AppData\Local\Temp\RtmpOCjWpG/R-3.3.1-win.exe 

 Running the installer now...

 Installation status:  TRUE . Removing the file:
 C:\Users\abcd\AppData\Local\Temp\RtmpOCjWpG/R-3.3.1-win.exe 
 (In the future, you may keep the file by setting keep_install_file=TRUE) 

We can not seem to find the location if the new R you have installed.
The rest of the updating process is aborted, please take care to copy
your packages to the new R installation.

Okay so the possible solution would be:

In my case, i had previously installed R in different directory and were using the same directory for R to work on.

Hence one can try below solution:

Post installing updated R version set up. One can open Rstudio and follow below step:

Code to update R from Rstudio:

    # installing/loading the package:
    if(!require(installr)) {
    install.packages("installr"); require(installr)} #load / install+load 
    installr

   # using the package:
     updateR() # this will start the updating process of your R installation.  It will check for newer versions, and if one is available, will guide you through the decisions you'd need to make.

Steps post installing R:

1. Click on "Tools".
2. Select "Global Options".
3. Under General tab, Look for R version and click on "Change"
4. A Choose R installation pop up will appear, Select the appropriate version which are installed on your machine.
5. Click "OK"
6. Close all R instances including R studio.
7. Now open R studio and Type version in console. Hollaaa, Hopefully this can resolve your problem.
