Are administrator rights needs to use the compiler in MPLAB IDE?
Users do not need to have administrator rights to access the compiler from within MPLAB IDE, but the MPLAB plugin (Universal toolsuite) does need to be able to read and write certain entries in the registry. If your user account does not have administrator rights, then you will need to ensure that the registry entry for: HKEY_LOCAL_MACHINE -> SOFTWARE -> HI-TECH Software has “Full control” set for this any folder and all subregistry folders. In the Windows Regedit program, right click on the above folder and choose Permissions. Select the appropriate Group or user name and review the Permissions.
