Hi,
I changed my computer, installed new copy Keil uVision4 and copy my project to new location. When I tried compiled, I get error:
assembling startup_stm32f30x.s... --- Error: failed to execute '.\ARMCC\bin\ArmAsm'
Keil info:
IDE-Version: µVision V4.14.16.0 Tool Version Numbers: Toolchain: MDK-ARM Version: 4.70.0.0 Toolchain Path: .\ARMCC\bin\ C Compiler: Armcc.Exe Assembler: Armasm.Exe Linker/Locator: ArmLink.Exe Librarian: ArmAr.Exe Hex Converter: FromElf.Exe CPU DLL: SARMCM3.DLL V4.70.0.0 Dialog DLL: DCM.DLL V1.9.0.0 Target DLL: STLink\ST-LINKIII-KEIL_SWO.dll V2.0.1.0 Dialog DLL: TCM.DLL V1.12.0.0
Did you uninstall the previous installation via Keil registration page?
To my knowledge, you cannot install two single license on one computer(duplicate CID). I'm not sure.
Looks like your still running the older version of Keil, perhaps you can reinstall the new version if a different directory.
