I am reposting this message as I got the following message with my original try. Sorry if you have received two postings. ------------------------------------------------------------------- 452 4.3.0 Requested action not taken: insufficient storage ------------------------------------------------------------------- Hi I have installed MPLAB to d: drive and getting dialogue box failed and other errors. I have looked at the beginners checklist and done the searches. I think I have some set up problems. Microchip tell me I have run out of memory. I have 64 Mg and have unloaded everything. Can someone please point me towards a site with MPLAB error codes, installation FAQ etc. I am converting from the 8051 family to PIC and the PICList has been a great help. Thanks in advance.
