I had this similar problem that you are facing now. The problem started when I tried to install an upgraded version (3.2.5). I applied a combination of tricks. But I think changing the repos with the following worked for me. Give it a try.

Give R and RStudio administrative privilege >> "run as administrator"
```
 - Or, Permanently Change: Using properties and Compatibility
```
Uncheck "use internet explorer library/proxy for HTTP" in RStudio and Restart.

Not necessary:

If you wish to change repos:

install.packages("dplyr", dependencies=TRUE, repos='http://cran.rstudio.com/')

I am using RStudio Version 0.99.491 R version 3.2.5 (2016-04-14) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64 (build 7600)

Hello @Akash Ansari I have done all the things that you mentioned and still i am facing the same problem: R version 3.3.3 R stduio Version 1.0.136 – Zaynul Abadin Tuhin Mar 19 '17 at 05:51
@ZaynulAbadinTuhin this is really confusing. I have never figured out what is the actual reason behind this. I searched over the internet quite a few times. But I have not found any single solid reason. I guess, the problem is due to RStudio. But the irony is that we can not think of R without RStudio. So what can we do now at this moment? 1) While waiting here, post this problem at https://support.rstudio.com/hc/en-us 2) If these don't work, try reinstalling R & RStudio with different versions. _(Please let me know if you have found out the reason behind this problem)_ – akash ansari Mar 19 '17 at 11:38
