I am deciding on which PIC Basic compiler to buy and have downloaded demos of both MikroBasic and PICBASIC Pro. The former runs perfectly but PICBASIC gives the error message; "PBPDEMO\PM.EXE cannot start or run due to incompatibity (sic!) with 64-bit versions of Windows". I have tried running as 'Administrator' and setting the app to run in XP compatibility mode but with no success.

Is there a solution or should I buy the MikroBasic product?

Thanks.
