RStudio startup error

Question

I am having problems opening RStudio, it worked fine before I got my mouse pad reconfigured. Here goes... When I open the program, it loads but appears blank. The menu tabs appear but do not populate when clicked. I've read a few answers to this one of which involved deleting the 'RStudio-Desktop' within the local files but did not solve the issue. I managed to run the RStudio diagnostic and below is the error message. OS is Windows 7.

I would be grateful if anyone can provide some insight regarding this.

Answer 1

Error 5 would suggest that the application is being written to those directories which does not have write privileges. Make sure those folders have write privileges.

You can also try running RStudio application as Administrator. To do so, Click on Start -> RStudio ( right click) -> Run as administrator.

Answer 2

I had similar problems installing R and RStudio on Windows 8.1 in C:\\Program Files. From Vista, Windows places multiple restrictions on systems folders such as %windir% and %ProgramFiles% .

Uninstall and re-install in a folder where you are not restricted, such as C:\\Apps or similar. You should hopefully have no further issues.
