I have a project of 8051 timer. In that the project file has extension of "uvproj" ... and it is not valid in UV3 version.. so how to open project,, and I need the debug file for running it in proteus software,, so how o generate that... .
uVision-4 uses a different project format from uVision-3.
As is usually the case, uVision-4 can open files from its predecessor, but uVision-3 cannot open files from its successor!
I don't think there is any facility to "downgrade" a project from uV-4 to uV-3
Look under the Menu Item Projects->Export. It appears that Keil can export in uV3 format although I have not verified it works.
