How to check whether PK51 Professional Developer's software is installed in the PC or not?
By clicking HELP---->ABOUT uVISION3 whether the window will show PK51.DLL, if at all it is installed????
Kindly help me.
Note that, for Help > About in uVision-3 to give details of the installed C51 toolset, you must have a C51 Project open.
If you don't have any project open, Help > About in uVision-3 just gives the uVision version - nothing else.
If you have a project open for another toolchain, Help > About in uVision-3 gives the information for that toolchain.
Help > About shows your licence details; if the details are blank, then you don't have a licence - ie, it's just an Eval version.
You can't have PK51 without a licence.
If you do have PK51, Help > About will include details of the components that are available only in PK51.
See: http://www.keil.com/c51/selector.asp for details.
If you think you should have a licence, you could contact Keil direct...
