Hi,
Do you get the same error if you click the [Compile] button instead of the [Compile and Program] button?
I'm trying to determine if the error message is comming from the compiler, the assembler or the programmer software.

EDIT: Ok, it's most likely from the assembler.....
The /s parameters is what controls the MPASM progress window. Looking at an older version of the MPASM documentation they don't mention that parameter/switch at all though. My guess is that the version of MPASM you have installed is too old....

Find the MPASMWIN.exe and double click it. What version does it say in the titlebar? My MPLAB installation is 8.85 and the MPASM version within it is 5.45 and I don't have the issue you mention.

You can download an installpackage including MPLAB 8.90 from MeLabs download page. If your MPASM version is older than 5.45 I suggest you do that and try again.

/Henrik.
