I am trying to run the C51 version 5 compiler on a Windows XP Professional machine. When c51.exe is invoked in a DOS box, the box hangs. I have tried emulating the DOS box as Windows 95, 98, 2000 and XP and the result is always the same. I do not want to upgrade the compiler to version 7 as this involves re-testing of several products for 6 weeks each. Does anyone know a way round this problem to allow C51 V5.x to run on a Window XP Professional machine?
Does the compiler generate any error or warning messages. When you get Warning 500 messages, it is important to look at the exact text, since it indicates the reason of your problem. If you cannot solve your problem send email to: support.intl@keil.com. The email should contain your serial number.
RE my message of 12/5/02: our copy with a dongle arrived at last, it works fine under win2k. Probably the old dongle is not suitable for this version, or the eval serial number is blacklisted.
Hi, We use the "MS-DOS C51 Compiler V5.02", from Keil Software, with "Sentinel Pro". We have been using this compiler for a long time, under Windows 2000 with Sentinel System driver. We now changed our OS for Windows XP, and the execution of the compiler is not working properly, it is full of intermediate messages like these ones, for example: /////////////////////////// PRIVATE ALLOCATION: LA 29D0000 - 1370 Bytes - handle 275B0E0 Leave loader...Exit loader [Enter loader...In loader] /////////////////////////// I already ran the Sentinel Medic and it says the Sentinel Pro Key is OK. The system just hangs up on the second compilation. Does anyone knows how to solve this problem ?
