A friend is trying to get Rtools installed correctly on her windows machine. It seems to install fine, but then at the end, she gets an error. The error below shows up in the Rtools installation wizard, and it suggest a permissions problem.
This is the error when trying to isntall Rtools on her machine
C:\Users\Chris\Documents\R\Rtools\gcc-4.6.3
Error creating registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Environment
RegCreateKeyEx failed; code 5
Access is denied.
Click Retry to try again, Ignore to proceed anyway, or Abort to cancel
installation.
Any ideas? Do you think this is the solution: http://support.microsoft.com/kb/327507
Looks more like a registry access problem to me - I think it's better to get that working correctly, then rely on RStudio/devtools to set the path dynamically when needed. That's less likely to cause clashes with multiple installed tools.
